What are you even talking about now? Pasteurization and cooking are different things entirely. A grilled steak is cooked, but not pasteurized. The milk in my fridge is pasteurized but not cooked.
yes, because this is the grill thread, how silly of deimos.
cooking a steak sous vide to completion would only require a few hours, and pasteurisation wouldn't happen, but this is not the case with eggs or anything that requires a >3h cooking time.

Yeah the "raw" bit was really more about flavor, responding to the initial flavor comment, and I could have phrased that more clearly.

At the same time, knowing that killing the bacteria doesn't destroy the Botulinum toxin always makes me cautious when dealing with raw garlic and any significant time in the danger zone, so I tend to be pretty conservative on that front. But yeah I don't want to spread bad info so I'll keep that in mind.
using fresh garlic in sous vide cooking isn't recommended as it gains a metallic flavour when cooked under vacuum. dried garlic would be preferable for this application.

The pot's metal and has a lot more surface area than just the surface of the water does. The point behind the cover isn't for thermal insulation, it's to reduce evaporation so you don't come home from work and find out that the water level dropped below the cutoff point and your 72-hour shortribs are now 112-degree food poisoning.


If the circulator can get whatever quantity of water you're using up to the target temperature, it can hold it there. Water has a *lot* of thermal mass.
foil will leak air, so the point you're going for isn't there.

not if they're in the water and reflecting heat back down (also reducing the surface area of the water in contact with the air), which foil being metal and generally unable to float reliably, it can't do as well.

I've read some things here about people cooking things in a bag, freezing the bag again, then somehow heating it up again before sear. Considering the amount of time it may take to thaw something in the water, does this save much time?
It wouldn't take that much time to thaw in a waterbath(more so if you have a circulating SV setup), though the usefulness of doing this would depend on the amount of time between steps 2 and 3, i.e. not very useful if it's all being done the same day.

I'd take Chef Steps' numbers with a grain of salt. Their 72 hour short rib was at 129°F and I found it to be insufficiently rendered.

Well, no, you're wrong.

Collagen can certainly liquefy at low temperatures, it just takes more time.

your link posted:

When you cook, collagen begins to melt at about 160F and turns to a rich liquid, gelatin. This gives meat a lot of flavor and a wonderful silky texture. When cooking it is important to liquify collagen.
...
NOTES: At 140°F changes are caused by the denaturing of collagen in the cells. Meat served at this temperature med-rare is changing from juicy to dry. At 160°F/ 70°C connective tissue collagen begins to dissolve to gelatin.

That page cites McGee's On Food and Cooking, which was originally written in 1984 (with a second edition in 2004), and therefore doesn't take into account the fact that a reader might be expecting to cook a piece of meat literally for several days at low temperature. McGee makes a lot of assumptions for the sake (I assume) of readability, which he---but roughly nobody who ever quotes him---is usually careful to qualify.

If you read a survey that cites more recent references, particularly one written with for an audience interested in s-v, you'll get different numbers. E.g., this article from Baldwin (which I quote mostly because it cites all the references):

...with a bonus...

...which turns out is pretty good advice.
the abstract is an interesting read, though I'm left wondering if there's any studies that have been done on the liquefaction rate of collagen over time. CS's diagram was somewhat accurate in an aggregate sense but lacks fine detail.

Botulism spores are destroyed at around 250F. Put your garlic in a pot with oil, bake at 275F for an hour. It's safe in the fridge more or less indefinitely after that, especially if it stays submerged in oil.
unless the pot was capped with a clean lid, it wouldn't be safe forever because botulinum is everywhere.

I see it like this:
Sodium chloride exists naturally, as in it can be harvested from the the sea or underground as a crystal, and soy sauce or fish sauce or worcestershire use natural ingredients that make up a sauce to get the flavour enhancing stuff.
Pure MSG is made large-scale by bacterial secretion into a tank and filtration and isolation of the compound. Maggi is made from enzymatic hydrolisation.

So the former sauces can all be hand made from natural ingredients, while the latter use industrial scale chemical processes to create a product that enhances the flavour.

I prefer the natural way to achieve the result not the "chemistry" way. I would rather use fish sauce or mushrooms or other ingredients that boosts the flavour by their natural glutamate content than sprinkle chemistry in my recipe.
Does that make sense? I feel like I may not be able to express the exact idea in my head as I am not a native speaker.

Also I mean no offence by saying "chemical", use whatever you prefer, I just can't express it better.
"this variety of chemical extraction is better than that variety because it uses smaller words" :downs:
glutamate is naturally present in meats; if it's enhancing the flavor of whatever you're eating it's because msg and glutamates are the best of friends.
also msg has like 1/4 the sodium content of Na2Cl

Hopper posted:

Yeah so I prefer to achieve a well tasting meal by combining (to put it in a very simple way) ingredients that are not synthesized in a lab if good flavour can be achieved without said synthesized ingredients.
Is that so odd?

How about a similar example:
Would you not rather eat strawberry yoghurt that gets its flavour from real strawberries rather than from strawberry aroma derived from chemical processing of wood chips?

I mean yes technically it makes no difference where the flavor comes from if the molecule is chemically identical. But real strawberries are still better than wood-chip derived aroma, wouldn't you agree?

And along the same lines i'd rather get the MSG from a leaf of seaweed or a bunch of mushrooms in my dish than from sprinkling in the lab grown stuff.

Is that really so odd? Yes you can use the MSG powder but wouldn't it be cool if you could reach the same result by using a certain the fruit/vegetable/fish etc. than to "rely on the help of a lab"?

Also: I am not a hippy, I eat frozen pizza and takeaway and stuff just like the next man. I am just curious why my reasoning seems so at odds with everybody else. I am pretty sure it has to do with the way Germans cook, though. I think a lot of people here generally have a high "aversion" against hormones, additives and other "artificial ingredients".
because you're making an arbitrary distinction about ~chemicals~ that smacks of pseudoscience. MSG has been around since roman times, if there were any data to be had on it's toxicity, it would have been nailed down and thoroughly dissected by this point.

e: also, you're making a very lame argument with the comparison to yogurt, yogurt is another example of something that wouldn't exist without human intervention, just like MSG.

yes, though any labels still attached will not survive the cook intact.

Yea I figured but the contrast is stark. The guides all act like its nearly the same thing. I don't think it's close. The ribs aren't bad by any means but it's not the same as BBQ. I think it worked well for pulled pork since theres very little surface area compared to the amount of meat. I think I'll stick to fish/pork/beef instead of trying to recreate bbq.
well they aren't the same thing, but that's because of the difference in cooking techniques(hot and semimoist vs warm and no moisture loss). your expectation of having a bark/smoky flavour on par with a piece of meat that's been sitting in smoke for =>4 hours isn't realistic.

With the ribs the meat is cured through, which is why the rib meat is pinkish-red color instead of your typical sous vide grey. If you want a clear differentiated ring, take a look at the chefsteps brisket that's also linked from the ribs recipe.
