• 1 1/4-oz. pkg. active dry yeast (1 tablespoon)
  • 2 tablespoons sugar or honey
  • 2 cups warm water 110°F., 45°C.
  • 1/3 cup nonfat-milk powder
  • 2 cups all-purpose or bread flour


  • (Container for mixing starter should be large enough to allow mixture to double in bulk. Always use a nonmetal container and plastic or wooden spoons. Metal containers and utensils produce an undesirable flavor.)
  • In a large nonmetal container or bowl, dissolve yeast and sugar or honey in water. Let stand until foamy, 5 to10 minutes. With a wooden or plastic spoon, stir in milk powder and flour. Small lumps in batter will be dissolved by fermentation process. Cover container with 2 to 3 layers of cheesecloth; secure with an elastic band. Set in a warm place free from drafts. Stir mixture several times each day. (Clear liquid that rises to the top of the starter should be stirred back into it several times a day.)
  • Let stand 3 to 5 days until starter has a pleasant sour aroma and is full of bubbles.


Note: If starter turns orange or pink, undesirable bacteria have invaded it. Mixture must be discarded.
To use starter, remove amount called for in recipe; bring to room temperature before preparing sponge.
Once starter is made, it may be refrigerated indefinitely,as long as it is replenished every 2 weeks.
To replenish starter, add equal amounts of flour and water. 
For instance, if you use 1 cup starter, replenish by adding1 cup flour and 1 cup water.  Cover and let stand in a warm place overnight.  Cover and refrigerate.
If refrigerated starter is not used for 2 to 3 weeks,remove 1/2 cup and discard, or give it to a friend. Replenish as directed above.
