It's cookie season again, and my old link for "the best cookies ever!" (according to Chad's students [*]) has died, so for your information: Skaarup’s Almost Perfect Chocolate Chip Cookie Recipe (you may need to scroll down).
Edit: that link appears to omit the [starred] substitutions, which are: for butter + butter Crisco, either 7/8 cup melted butter, or 1 cup butter Crisco; for 2 teaspons baking powder, 1 teaspoon baking soda + 1 teaspoon corn starch. (I've never tried either of these.)
Edit again as note to self: dark brown sugar is better than light brown.
As you know if you watched that Good Eats episode, the shortening, the brown sugar, and chilling the dough means that these are poufy, dense, and a bit soft.
(I personally like a #30 scoop rather than Alton Brown's preferred #20, which gets me 32 cookies, but I concur with Alton Brown that parchment paper is better than the recipe's suggested wax or foil.)
[*] People made nice noises about them at the party yesterday, so it's not just starving students who like them.
