The absolute best biscuit recipe is from Cook's Illustrated. I modified it for whole wheat flour and dried buttermilk, because I only eat whole grains and dried buttermilk is more convenient. Try it with whole wheat, I think you will like it. If you want to use white flour, you might need to decrease the liquid somewhat, because I think I increased it because whole wheat absorbs liquid.
Whole Wheat Fluffy Biscuits (Cook's Illustrated Magazine, modified)
Dough
2 Cups Whole Wheat Flour
6 Tablespoons Saco Buttermilk Blend Powder
1 Tablespoon + ½ tsp aluminum free baking powder (Rumsford)
½ teaspoon salt
½ teaspoon baking soda
3-4 Tablespoons cold butter, cut into ¼ inch cubes
1 ½ cups skim milk
To Form and Finish
1 Cup Whole Wheat Flour
2 Tablespoons Butter, melted
Adjust rack to middle position and heat oven to 500 degrees. Spray 9 inch round cake pan w/non-stick cooking spray, set aside. Generously spray inside and outside of ¼ dry measure w/non-stick cooking spray.
Sift dry ingredients, place in food processor. Scatter butter cubes over mixture; pulse until it resembles pebbly, course cornmeal, 8-10 1 second pulses. Transfer to a medium bowl. Add milk and stir with spatula until just incorporated (batter will be wet and lumpy).
Using a ¼ cup dry measure, scoop dough and drop into flour on a baking sheet. Repeat until there are 12 mounds. Dust tops w/flour. With floured hands, gently pick up a piece of dough and coat it with flour. Gently shape into a rough ball, shake off excess flour and place in prepared cake pan. Repeat, arranging 9 rounds around the perimeter and 3 in the middle. Brush with hot, melted butter, avoiding flattening the rounds.
Bake 5 minutes at 500, then reduce temperature to 450. Bake until golden brown, 15 minutes longer. Cool in pan 2 minutes, then invert onto rack. Turn right-side up and break apart. Cool 5 minutes longer and serve.
These biscuits are best served warm.
