1 c  Nonfat or lowfat milk
3 tb Unflavored yogurt (we used
Nonfat)
1 c  All-purpose flour

In a 1-quart pan over medium heat, heat milk to 90-100 degrees. Remove from
heat and stir in yogurt. Place in a warm 3 to 6 cup glass, ceramic, plastic
or stainless steel container with a tight lid. Cover and let stand in a
warm place until mixture is the consistency of yogurt and a curd has
formed. (You can test the mixture by tilting the container. If the mixture
doesnt flow freely when the container is tilted, its ready.) The curding
process takes about 18 to 24 hours. Youll need to check it periodically.
If some clear liquid rises to the top of the milk, stir it back in. NOTE:
If the liquid turns pink, discard the batch and start again. Once the curd
has formed, add the flour and stir until smooth. Cover again and let stand
in a warm place until the mixture is full of bubbles and has a good sour
smell. This should take about 2 to 5 days. Again, if some clear liquid
rises to the top stir it back in. If the liquid turns pink, discard the
batch and start again. When the mixture is ready, you can keep it covered
and store it in the refrigerator until you need it. The recipe makes about
1 1/3 cup starter.
