chemistry lesson

While trying to make cookies today, I learned a nifty little fact. Fifty degrees TREMENDOUSLY changes the way cookies bake! At 400 degrees, oatmeal/butterscotch chip cookies flatten out and burn to a messy crisp. At 350 degrees, they bake to a perfect little golden round deliciousness. I'm not much on following rules to the exact letter, but I guess the temperature on the recipes do have a purpose and need to be "obeyed." :-)
