Buttermilk Biscuits

Alton Brown's southern biscuits recipe from the Food Network showed promise. I didn't have buttermilk so I used the 2 tbsp white vinegar + 1 c. milk as a substitute. Other than that I followed the recipe the best I could. The dough was very sticky so I might have added too much flour during the kneading and rolling step.

They rose well but had a tough bottom because of the dark cookie sheet. According to the White Lily biscuit tips, a shiny cookie sheet would help the biscuits brown on the top and bottom evenly rather than just the bottoms with a dark cookie sheet.
