Waffles

Mark Bittman - How to Cook Everything
The best possible waffles, if you can remember to start them the night before.
8 servings
¾ t yeast
3 c flour
1 ½ T sugar
¾ t salt
3 c milk
12 T melted and cooled butter — yeah, that’s a stick and a half
¾ t vanilla (optional)
3 eggs, separated
Before going to bed, combine dry ingredients and stir in the milk, then butter and vanilla. Cover with plastic wrap and set aside overnight at room temperature.
Brush waffle iron with oil and preheat. Separate the eggs and stir the yolks into the batter. Beat the whites until they hold soft peaks. Stir them gently into the batter. Spread a ladle full onto waffle iron and bake about 3 to 5 minutes or until done. Serve immediately with maple syrup (no butter needed).
