  1                cup  sourdough starter
  1 1/4           cups  unbleached white flour
  1                cup  water
     3/4           cup  whole wheat flour
     1/3           cup  powdered milk
     1/2           cup  brown sugar
  2          teaspoons  baking powder
  1           teaspoon  cinnamon
     1/2      teaspoon  salt
     1/4           cup  butter
  1                     egg -- beaten
     1/2           cup  apple -- chopped, peeled
     1/4           cup  chopped nuts

Preparation:

1. Combine the first 3 ingredients in a large bowl, cover loosely and allow to stand in a warm place up to 24 hours, depending on how sour you want the muffins to taste. 2. When ready to bake, sift together all the dry ingredients into a second bowl and cut in the butter until the mixture resembles coarse meal. Add the egg to the starter mixture and stir it quickly into the dry mixture. Don not beat; stir only enough to mix everything. The batter will be lumpy. Fold in the chopped apple and nuts and pour the batter into well-greased muffin tins, filling each no more than 3/4 full. 3. Place the tins in a warm place and allow the muffins to rise for about 20 minutes, then bake in a preheated 400F oven for about 30 minutes. Do not underbake.
