That's a good question. It is a sour dough starter I got from a friend about 5 years ago. His grandmother passed it to his mother who passed to him. Probably just a sentimental think. It makes a bread like nothing I have had before. Just heat in a microwave with butter and very good. It wont toast. Here is the recipe that came with it. I put bread in oven before turning on then start timer when gets to temp. Leave in pans until cools about 30 minutes before trying to remove.
6 cups flour
1/2 cup sugar
1/2 Tps salt
1/2 cup oil
1 1/2 cup warm water
1 cup starter - Let sit out 6 hours before using
Mix all ingredients in large bowl, grease another bowl. Put dough in greased bowl and turn over once to grease all sides. Cover lightly with foil and leave on the counter top 8 - 12 hours. Punch down the dough and knead a little. Put into two greased bread pans. Brush with oil. Let stand 8 - 12 hours. Cover with waxed paper. Bake at 300 degrees for 30 - 40 minutes or until brown. Remove from pan, brush with butter and cool on rack. Store in refrigerator.
