Ultimate Mango posted:Any reason why a whole brisket would be unsafe to sous vide? I know that very thick cuts will not hear to core safely, but I figure a brisket is thin enough to not be a problem. The downside of doing a brisket sous vide as opposed to smoking is that you get neither a smoke ring nor bark. If you just want a bunch of beef to shred that's probably not a big deal. But it's worth pointing out that it doesn't really produce a similar result. Some people are happy adding liquid smoke or the equivalent to try to replicate the flavour of smoked meat. I'm not a fan of this, but your mileage may vary. You can also smoke a brisket for the first couple hours and then finish it in the puddle machine---smoke ring formation only happens before the meat hits around 140 F/60 C so if you put a probe in the surface and pull the brisked when the first quarter inch/cm or so hits temperature you'll get all the smoke ring you'd have gotten if you'd done the whole thing in the smoker. Bark formation, however, is something that needs a lot of time in a fairly dry environment to get all those proteins to polymerise. I don't know any way of faking/expediting the process.

Chemmy posted:I get niman ranch pork rib chops and vizzle at 135 for an hour or so before searing hard like a steak. In other news, my cheapass Rival sealer went tits up. Vacuum pump is still working fine, but the heating element isn't heating up at all. According to my amazon history, I bought it a little over four years ago. Just got another one. The low end model (or at least the cheapest one you can get from amazon) is different today. It's a little smaller all the way around. The vacuum pump seems stronger---evacuates a bag much faster. That's theoretically an improvement, but somewhat counterintuitively I prefer the weaker pump, because it makes it easier to bag up eggs, sauces, and other wet poo poo. The heating element also seems to take less time to seal. Overall the build quality seems a little better all the way around. Just throwing that out there because I've spoken favourably about the US$30 Rival sealers before. I can definitely deal with getting four years of continuous (several times a week) use out of a US$30 kitchen appliance (it's nothing compared to what I've spent on rolls of bags in the same time), but YMMV.

Mikey Purp posted:I think a lot of the discrepancies have to do with sous vide being a relatively new cooking method in the realm of the amateur chef. You see a lot of people experimenting and while there are definitely some leaders in the field (Doug Baldwin, Nathan Myrvold, Kenji Alt-Lopez), there's also a lot of static of different people of wildly varying expertise either knowingly or unknowingly trying new things. This kind of poo poo has always been true and it's something everyone's more or less aware of, but with more modernist or molecularist or whatever the gently caress poo poo getting into the mainstream there's this tendency to believe cooking has suddenly become all lol science all caps exclamation point. And that kinda leads to this expectation that every dish can be reduced to a beep boop formula that always produces beep boop identical results. But that's never going to be true until you have identical cooks, identical ingredients, and ideal spherical people eating. And gently caress that.

Ola posted:What's the right temp/time? I'd like to perfect my sous vide egg, in the past I've only ever gotten nice yolks. You know how if you're cooking something in the oven you're aiming at one target internal temperature but when you're cooking in a puddle machine you end up looking for a much lower number? That's because the number you generally use for oven cooking is the one that gets you, in principle, an instantaneous 6.5log10 (or whatever) reduction of whatever pathogens you're worried about. And when you're doing it in the puddle machine you're getting the same reduction from a lower temperature but over a longer time. And what that's telling you is that at your sous vide temperature at any given moment you might have just killed a random individual pathogen that might be in the food, but the chances are small enough that you have to keep rolling those dice for a couple hours until you're confident that all of those pathogens (or all but one in 106.5 of them) have crapped out. When you're looking at something like the texture of a vizzled egg you're looking at basically the same game, only with a couple of particular bonds in some proteins in the white or yolk. So any temperature that will denature those proteins at all will, mumble mumble some caveats you really don't give a poo poo about in the kitchen, eventually denature enough of them to set the eggs however the gently caress you want if you give it enough time. Looked at a slightly different way: you can still overcook poo poo in the puddle machine, it's just that at the kinds of temperatures you're usually using in a water bath the window for correct/desired doneness is wide as hell because the processes you care about are going slower than Christmas compared to `conventional' cooking.

Bob_McBob posted:I have a Demi and several ICs, and I actually think the Demi would be preferable for many people simply because it's a compact self-contained appliance. From an engineering standpoint I think the existing crop of ICs are probably ICs only because they're low-end copies of ICs used in a laboratory environment (where the difference in performance of an IC and something heating via liquid convection is relevant, and where the liquid is not necessarily water). For home cooking you'd probably be better off, from a maintenance standpoint, getting rid of the pump entirely and using a larger heating element (like an aquarium heater).

Argyle posted:Huh. Mine were brown and well-done all the way through, right out of the water. Basically when you see grey or brown meat what you're looking at is myoglobin that's denatured and formed one of a couple different compounds, depending on what the iron in the myoglobin happened to bind with. What the iron was bound to before the myoglobin was denatured is one of the factors that determines what happens when it does denature, and it also influences how likely it is to denature at any given temperature. Oxymyoglobin, which is the pinkish colour of the surface of raw meat in air, will (all else being equal) denature into hemichrome (which is the greyish colour you probably associate with well-done meat) at a lower temperature than deoxymyoglobin, which is the more purplish or bluish colour you see in the interior of meat. Since ground meat is nearly all surface, nearly all of the iron in the myoglobin will be in the form of oxymyoglobin, and so will turn greyish sooner than meat a cm inside e.g. a steak (where the myoglobin will mostly be in the form of deoxymyoglobin) even if the two are at exactly the same temperature and doneness. So tl;dr: don't rely on colour to judge doneness. If your burgers were coming out too tough at 135, chances are it was either just poo poo ground beef or it was just plain too lean. You can do a lot with lovely ground beef and very lean ground beef, but a burger, even done in a puddle machine, really isn't one of them.

Jarmak posted:This sounds dumb as hell, vapor pressure inside a crimped tinfoil cover will do way more to slow evaporation then ping pong balls floating on the top. Foil (or a lid) will not affect evaporation at all per se---you're just relying on the lid to allow the water vapour to condense and drip back down into the container. Putting ping pong balls (or anything else) in the water will be less effective as a condenser than foil, but unlike foil it will actually change the rate of evaporation in the first place: the rate of evaporation is directly proportional to the surface area of the water. Ideal space packing of uniform circles on a flat plane is around 91% (ideal hexagonal packing) and absolute worst case (each circle inscribed on a square in a uniform grid) is around 75%, so the balls are going to reduce the amount of evaporative loss by about that much.

Jarmak posted:Holy poo poo guy, evaporation occurs when individual molecules become sufficiently energetic to escape the IM of the other molecules, thats why ln(P2/P1)=(ΔHvap/R)*(1T1−1T2). You don't need a loving pressure cooker to achieve pressures and gas concentrations which significantly slow evaporation at temperatures that are nearly half of the boiling point. Doing some really rough math in my head that should be something like 1/5 of the vapor pressure at 140 (which would mean its ~1/5 atm). Jarmak posted:This sounds dumb as hell, vapor pressure inside a crimped tinfoil cover will do way more to slow evaporation then ping pong balls floating on the top.

Honestly, I think it looks pretty neat, and it would be awesome to just toss some food into it before I go to work, and have it ready to eat by the time I come home, what do ya'll think? I mean I'm totally not the target market for this thing (Michael Pollan endorsement lol) but it like they're trying to be the breadmaker of the sous vide market.

Jarmak posted:Anyone got a source for the " acid makes pasteurization take twice as long?" It seems to run directly counter to everything I do with fermented charcuterie where acid means safe. The behaviour is due to a mechanism called acid tolerance response (the search term you want if you're looking for one) or ATR in bacteria. The simple version is that any time a bacteria is exposed to an environmental shock it'll respond by trying to produce proteins that will enhance its survivability. If the shock is large enough (like if you're dumping the typical foodborne pathogen into distilled vinegar) it'll just kill the bacteria outright. But in something like a marinade you're typically not lowering the pH throughout the dish enough to kill all the bacteria. The surviving bacteria produce ATR proteins, and as a result are more resistant to other environmental stresses (like heat). On the other hand when you ferment something, you usually start out by making sure conditions favour proliferation of the fermentation bacteria---making the environment artificially saline, adding a culture of fermentation bacteria, or using something with a high natural prevalence of the bacteria you want (like cabbage). So initially you're just relying on the good bacteria to outcompete the bad bacteria. Once they get going they're eating sugar and making GBS threads acid---that's what makes them fermentation bacteria. Initially the pH isn't low enough to retard bacterial growth, but that's okay because all the bacteria are your guys. Eventually the acidity will retard and stop the activity of the fermentation bacteria, but then you're reasonably confident that the pH is low enough to prevent other bad poo poo from getting a foothold---because you know that the pH is low enough to gently caress up your fermentation bacteria.

Random Hero posted:So I bought some flank, skirt and flat iron steak today that I plan on sous vide'ing tomorrow or Saturday at my family's house and I'd like to prep and vacuum seal them before so I have less to take with me. What seasonings (s+p, herbs, butter, oil) can go in with the steaks up to a day before actually starting the cook? I figure butter and dry herbs are fine, but I'm more concerned with the salt. Any advice here? Salt's fine assuming you aren't adding enough to cure the thing. In general you want to either salt immediately before searing or an hour or so (or more) before searing. The former gets you slightly better crust and slightly less of a flavour boost from the salt (that is, not just saltiness, but the general flavour accentuating action). The latter gets you better flavour enhancement. You don't want to salt in the window in between `immediately' and `about an hour' because you'll be giving the salt enough time to draw water out of the meat but not enough time for it to be reabsorbed. I believe Our Lord And Savior Kenji did a blog post about it and I'm sure someone will be along presently to link it.

Chef De Cuisinart posted:Kenji's right, added fat is bad. If you were to put 1T of butter in a bag with your steak, which is about what you'd use for a pan sauce, you will dilute herby flavor compounds. I mean I wouldn't put butter in with most meats and I really don't `get' trying to use a bag in a water bath for poaching or braising (since poaching and braising work perfectly well for what they do in their `traditional' forms). But if you're trying to argue that oil in the bag is bad you really have to account for the fact that all kinds of poo poo is oil soluble but not water soluble, so in addition to whatever notional dilution you're causing you're also releasing a lot of poo poo that you wouldn't otherwise be. I mean you wouldn't try to bloom spices in water versus oil, would you?

Jarmak posted:Yeah that might work if your goal is to make the butter taste better, but it doesn't matter how many compounds from the herbs get dissolved if they all stay trapped in the butter along with the compounds that would have dissolved without it, as well as pulling fat soluble compounds out of the meat. Further, you can't have it both ways. If the oil isn't penetrating into the meat then there is no mechanism for it to `pull fat soluble compounds out of the meat'. A solvent can't dissolve poo poo where it ain't. That said, essentially all techniques based on submersion of meat in flavoured liquids (brining, marinading, braising, and so on) are predominantly surface phenomena. So if your argument is that you're probably better off doing whatever you're going to do with butter while the steak (or whatever) is in the pan rather than in the bag I agree. But that's not what Kenji was saying, and that's not what I was responding to.

Choadmaster posted:In fairness to Kenji, you're actually arguing against Jarmak's slightly-off paraphrasing. Kenji doesn't say butter pulls flavor from the meat, but that it absorbs the flavors of the herbs and seasonings you put in with the meat, such that you're flavoring the butter (most of which isn't going to make it to anyone's mouth) rather than the meat. Kenji posted:Intuitively you may think that adding a flavorful fat like butter or olive oil will in turn help create a more flavorful steak, but in fact it turns out that you achieves the opposite goal: it dilutes flavor. Fat-soluble flavor compounds dissolve in the melted butter or oil and end up going down the drain later. Similarly, flavors extracted from aromatics end up diluted. For best results, place your seasoned steak in a bag with no added fats. I think the dilution of herb flavour is a non-issue (just add more herbs) and, as I commented in my first response on the subject, I'm sure the dilution of fat-soluble flavour compounds from the meat is something that happens. But it's almost certainly irrelevant (because it's not going to happen much---because it's largely a surface phenomenon and therefore can't possibly affect the overwhelming majority of fat-soluble flavour compounds in the meat), and to whatever extent it is happening, it is necessarily happening simultaneously with the transport of fat-soluble flavour compounds from whatever herbs are there into the meat.

Chef De Cuisinart posted:It does become an issue of cost in a commercial environment. Chef De Cuisinart posted:It isn't a largely surface loss, if you're salting before bagging because osmosis. Bottom line, there's no reason to add fat to your bag, and at least 1 definite reason to not add it. But all that diffusion is almost entirely at the surface as well. Ever cured a piece of meat? Observed how you can literally pack a piece of meat in salt and yet it still takes weeks or months to dry out? That's because the diffusion of salt through the meat is that slow. And salt is pretty small and well-behaved so those Na+s and Cl-s get transported about as well and as quickly as anything will. Certainly more quickly than any bigass organosulfur compounds (like you get out of aliums) or god help you diterpenoids (from e.g. rosemary or some of the fat-soluble poo poo in the meat). So no, really, all that diffusion is primarily a surface phenomenon. And I want to point out, again, that I'm not arguing that you should add butter (or anything else) to the bag when you're putting meat in the puddle machine. Just that people keep throwing out theoretically science-y sounding arguments that contain fundamental errors.

You can even SV some fatback with your aromatics and salt to have a quick 1 day lardo, as opposed to waiting a week.

Jarmak posted:This is dead wrong, curing takes that long because of the drying process not because of salt transport, which happens incredibly fast. The actual curing process only takes a day to a week to finish depending on the size of the meat, the rest is drying, if it actually took a month for the salt and nitrite to transport you'd be loving dead. Note that this is for salt in a wet brine, not a rub (as noted in the text). The reason why food safety isn't an issue is because (assuming you're using a properly-prepared piece of meat from a healthy animal) spoilage is going to happen, just like curing, from the surface in. Jarmak posted:Seriously gently caress off with your "I'm going to read a straw man into this four word statement so I can wave my scientific dick around and distract everyone with the fact my advice was wrong". I paraphrased the article from memory and forgot it was the herbs and not the meat that was the issue, the point was don't put butter in the bag. My scientific training may not be as good as yours but its good enough to spot a jackass who's very good a one field or another so thinks he knows everything about everything and uses bluster and jargon to bludgeon people who don't know any better into thinking they know what they're talking about.

The longest part of the curing process is the drying, not the salt transport, you don't even hang the stuff until its fulled cured. That link stops at 24 hours so its pretty useless for this discussion, also he's talking about brining, which is a super inefficient method of curing because of equilibrium issues with the solution unless you continuously add more salt (which you know you're supposed to do if you're trying to cure something big with salt in a brine, and he didn't), not to mention you said "packed in salt" which is how I do all of my cured products.
