1 c. starter
2 1/2 c. water
5 c. flour
3 tbsp. shortening
2 tbsp. sugar
1 tsp. salt
1/2 to 1 tsp. baking soda

Combine starter, water and flour. Let stand overnight. Next day, add shortening, sugar, salt and 1/2 to 1 teaspoon baking soda, depending on sourness of starter. Stir until well blended. Turn out on well floured surface. Knead thoroughly, adding more flour as needed. Divide dough and make into loaves. Put into 9 x 5 x 3-inch pans. Let rise until double in size, as long as 3 hours. It rises slower than regular bread. Brush with butter.

Bake at 400°F for 40 minutes.
