Dissolve yeast in warm water. Add a pinch of sugar. Leave 10 minutes to proof - yeast should show that it's active by creating a foam, and bubbling.
Add all ingredients to a large mixer bowl and beat with a rotary beater until smooth.
Cover and let rise in a warm place, free from draft for 1 1/2 hours. Stir down batter. Cover and refrigerator overnight.
Stir down batter. Pour onto center of a hot, seasoned waffle iron.
Bake each waffle about 5 minutes, or until steaming stops.
