An Alton Brown must-see episode!
Tonight, FN is airing Alton's "Three Chips for Sister Marsha" episode. The show details the chemistry involved in creating three different types of chocolate chip cookies from the same basic dough. You change the fat, the temp, etc. in order to create the cookie texture you desire: soft, chewy, crisp, etc. Very informative, and I have cooked for decades and decades!
