Sour Dough Starter and Feeder

Starter
1 medium potato
1 pkg. dry yeast
1 TBS. sugar
Peel potato and boil it in enough water to cover until soft. Drain off and set aside the water. Mash the potato. Add enough water to the water that was set aside to make 2 cups of lukewarm liquid, then add the dry yeast. Stir in the potato and sugar. Let the mixture stand in a glass or crockery container, loosely covered, for 2 days stirring occasionally. After 2 days the starter should be refrigerated for 5 days. Every 5 days feed the starter.
Feeder
3/4 c sugar
3 TBS instant potato flakes
1 c. warmwater
Feed this to starter every 5 days and let set on counter for 8-10 hours and either give a cup of starter away or use the one cup of starter to make sour dough bread.
