Searing steak: yep, it's a myth.

The reason you sear steak is to cause what are known as the "Mailliard reactions", a complex waterfall series of reactions that happen when you expose meat proteins to temperatures over 140C. That decomposes the surface of the meat into a very complex collection of extremely tasty aromatic compounds (including some of the compounds responsible for the taste of coffee and chocolate).

If you're interested in this sort of thing, a) the experiments have already been done, b) I recommend Harold McGee's "On Food And Cooking" as a solid starting point. "America's Test Kitchen" is also good.

This is also the kind of thing I was thinking could be covered in a "Cooking for Hackers" series.
