Dry ice and a cookie sheet indeed.

Alinea at Home is one of the blog sites in my foodie feeds, and her recent experiment with some of Alinea's recipes has shown that using her countertop, followed by a towel, dry ice, then a cookie sheet on top can reproduce the effects of an anti-griddle...
I'll be using a laser read to determine what the temperature of the surface actually is, since I believe the temperature of dry ice much lower than -40 degrees of the anti-griddle.
Also, if anyone has any good sous vide recipes, this will be an experimentation weekend for me...
