Buckwheat Pancakes

Grandma loved buckwheat pancakes and were often a Sunday staple. I have yet to make them taste as good as what grandma made.

1 package yeast
1 cup water
1 cup buckwheat flour
1 tsp. sugar
1 tsp. salt

Sprinkle yeast over one cup warm water to dissolve. Add buckwheat flour and mix thoroughly. Cover bowl and let rise in refrigerator eight hours or overnight. Mix in sugar, salt; add enough water to thin batter.
