Shouldn't water be flowing in a good sous vide cooker to maintain even temperature throughout or am I talking out my butt?

I think you are correct, the commercial models are marketed as circulators so they have both the heating element and a way to move water around to ensure even temperatures throughout the water tub.

Yes, that is correct. I used an aquarium circulation pump for this (http://fab.cba.mit.edu/classes/863.14/people/matthew_arbesfe...). They go for about 10 bucks on Amazon.

I've done some sous-vide after watching Chef Steps[1] on youtube. I just used a water thermometer and ziplock bags, which they have some examples of in their videos. My smallest stove top burner at its lowest setting gets water up to 117F. The salmon video they had the temp at 109, but I tried it anyway. It turned out amazing - I'd definitely do it again. I also tried steak, but bought a cheap cut, and it turned out…

I have a Sous Vide Supreme[1] and it's pretty much the secret weapon for making cheap beef tasty. Even cheapo chuck can do really well in one of them if you let them go for a while. What's nerdy-cool about it, I think, is that if you're quick, you can seal a steak with no air bubbles whatsoever and the steak will remain bright red while it cooks. Obviously you sear it after, but watching people's eyes bug out a littl…

Traditionally, that has been barbecue, no?

Or long, slow cooking in general. The "secret weapon" property of low-temp cooking is not so much that it makes cheap cuts taste better, but that it makes them taste like expensive cuts of beef --- not the same thing.

The best-tasting cuts on a cow actually tend to be the cheapest anyways.

Hey arbesfeld, I really like that project, and the nice writeup really presents it well. But especially as people might use it for inspiration for their own temperature-controlled cooking projects, I think the lack of a proper isolation of the mains-powered parts is a little bit worrying. For the next project, or maybe as advice to the random person looking at the HN comments, here's what I normally do: Try to minimi…

I really like this comment. It's kind and encouraging, providing actionable and constructive advice even while pointing out a rather serious flaw.

Sous-vide is interesting to me but only seems worth it if you eat a lot of meat. Am I mistaken?

Like traditional BBQ (e.g., low-and-slow cooking over coals) sous vide is most interesting when applied to meat, especially cheaper cuts that would normally have to get boiled, braised, or roasted to within an inch of inedibility before being soft enough to eat.

That being said, my absolute favorite thing to prepare sous vide is carrots. Lots of other root vegetables (turnips, burdock, sunchokes, new potatoes) can similarly be cooked in a water bath to a temperature just high enough to soften them without extracting flavor or nutrients via boiling, steaming, or sautéing. I've also had good luck with green beans, asparagus, and broccoli rabe.

Finally, if you're pescetarian seafood is also a great option. I'm not sure I'll ever cook lobster any other way after seeing what whole (shell-on) lobster tails are like cooked sous vide with a healthy dollop of butter.

Pedantic: you built a really cool PID-controlled immersion heater, not a "sous vide cooker". Sous vide is the technique of preparing food in a vacuum. Placing food in a zip-top bag and displacing the air out might give you a reasonable water-product interaction surface, but it does not form a vacuum, and therefore is not cooking en sous vide.

Question for sous-vide aficianados. Are you not worried about the chemicals going from plastic to your feed ?

I grew up knowing that, by and large, the less manufactured stuff you put in your food the better the food is for your body.

So, it seems highly dangerous to me to take natural piece of food, wrap it in a highly complex chemical compound (plastic), heat it, and then consume it.

I own the Sansaire, but right now I'd recommend the new Anova one that comes with an app and is well-reviewed by Serious Eats. http://anovaculinary.com/products/anova-precision-cooker http://www.seriouseats.com/2014/05/new-anova-precision-cooke...

Do you know if they've released the android app yet? You can use it without (has a little wheel to set temp), but the monitoring and timing obviously don't work.

I don't know, unfortunately.
