When the environment is at a fixed temperature? If anything, increased diffusion through permeation while submerged in water would decrease cooking time, but I don't think the different properties of density alone between water and oil is any more than negligible in this context.

Shall we consult Harald McGee?

Not really. I mean, I realize the difference in density will affect conductivity within water itself, but I'm not sure if overall heat transfer would decrease very much due to density difference between water and oil at such low temperatures. I think oil also has viscosity and molecular size working against it in terms of overall heat transfer. That's not to say that density isn't a factor at all, but I'm just saying that there are other factors involved, especially in regards heat transfer between miscible and inmiscible substances.

I just thought of water's higher thermal expansion coefficient than lipids, so I wonder really how much difference there is in density between water and oil at 180 degrees. I'm going to drop some butter in 180 degree water and see what happens compared to when it's dropped in chilled water.

Interesting, I've never thought of trying that even though it seems so simple. Does it maintain the shape of the egg, or just keep the egg in one piece instead of it dissipating throughout the water? Poached eggs are a beautiful thing....

180 degrees is too low of a temperature to change the density of water much.

Much confusion over cooking sausages.

Fat breaks at about 160-165. As Kyle said, a good sausage is a careful mixture of meat with fat suspended in it. So the goal is to cook the meat and brown the casing while not rendering much of the fat out. In fact, something like a thuringer, you should still see little pieces of backfat suspended in the meat.

Medium-low saute in a covered pan for me. Don't let the skin burst but I will stick a Thermapen in to check temps. Natural casings will quickly seal a little pin hole like that. I bring to internal temp of 155 with the natural casings nicely browned. Nothing like the perfect texture of a sausage you stuffed with the snap of a well cooked natural casing when you bite into it.

This is a dumb question, but think of it as a free bump. I'm making scallops from Ad Hoc this weekend. However, I don't have a steel fry pan like he suggests using (it's on my purchase list). Should I use either my Le Creuset cast iron fry pan or an All-Clad stainless sauce pan (would obviously not crowd them while cooking)?

I would pick the stainless as I've noticed my sole Le Creuset doesn't seem to like to quickly sear/brown things. I don't know if that recipe calls for doing the scallops like that, but if so, there's my advice.

Cast iron. What kind of steel does he suggest? Black steel is pretty much the same as cast iron. Stainless is different. Stainless also kind of sucks. I use black steel for almost everything. Love it.

If your cast iron pan can't sear, that's pretty fuckin lame.

really? Are you sure it's hot enough? It does take longer to reach a higher temperature. I find my Le Creuset to be fantastic for a quick sear/brown and use it routinely for anything braised.

he suggests to NOT use non-stick for a good sear/crisp outside, and instead stainless. I believe the picture is just an All-Clad fry pan.

I'm just curious since I don't want the high sides of the stainless pan to change the way they cook or anything. My initial plan was the cast iron.

Yeah, Lame-o!!!

Seriously, though, Pio, is the inside of the Le Cruset enameled? My unenameled Lodge is the most nonstick pan I have when it's preheated. I also have a classic steel pan, but like what Matt said, they behave the same.

Black steel =! nonstick. They are usually made of carbon/steel alloy. They are truly ideal for searing but don't get washed like regular pans. Instead, they get seasoned the same way a cast iron pan does. They are generally inexpensive, you might look into one.

sounds interesting. I'll take a look sometime, but I need a bigger Le Creuset and a bigger stock pot first.
