Ned's healthy biscuits

Ned has cobbled together a recipe for nutritious biscuits (not cookies for our UK friends). Here is the recipe:

1 cup buttermilk
2 tsp sugar
1/2 tsp baking soda
1 TB baking powder
2 c. flour (1 and 1/3 c whole wheat, 1/3 c oat bran, and 1/3 c high gluten unbleached)
7-8 generous pats cold butter (about 1/4 pound)

Turn oven to 450, then begin. It is important to put the biscuits into a hot oven as quickly as you can because the baking powder and baking soda starts to react with the buttermilk quickly.

Mix dry ingredients
Cut cold butter into small pieces and dump into dry ingredients. With your hands, mash the butter into the dry stuff until you have made sort of a meal, and the butter is mixed. Oil a baking sheet. Check the oven. Is the temp near 450? Then go. Add and mix buttermilk, then turn the dough onto a baking sheet and knead a few times. Add more flour as needed. Cut about 2 inch rounds of dough with whatever you have. Ned used a glass dipped in flour.
Place the biscuits (about 15) onto the baking sheet and put them into the 450 oven. Bake about 15 minutes then check. Check oven for correct temp also. Take out when biscuits are nice and brown. Fantastic and loaded with fiber.
