Sourdough Doughnuts

Mix starter, milk and flour until smooth. Add eggs and oil and beat well. Blend in small bowl the sugar, salt, soda and flour. Mix well into dough. Turn out onto 1 C flour and knead lightly until most of flour is worked in (dough is soft.) Place in greased bowl and turn to grease too. Cover with wax paper and let rise until doubled. Then turn onto 1/2 C flour on board. Pat to 1/2" thick. Cut and put on well floured sheet and let rise until doubled. (Don't cover!) Fry only 3-4 in hot fat at once and fry raised side (top) first turning only once. Drain. Makes 4 doz.
