1 stick butter (4 oz.)
8 oz. pastry flour
1 oz. sugar
1/2 tsp. (.08 oz) salt
1 T. (.05 oz) baking powder
3 eggs, separated
2 cups milk or 1 c. buttermilk / 1 c. sweet milk
1/4 fl. oz vanilla or 1 tsp
Note: If using buttermilk, reduce baking powder to 1 tsp (1/16 oz) and add 1 tsp (5 grams) baking soda instead. 2 cups milk = 12 oz aquatronic weight. If using liquid scale, switch to fl. oz. You will need a scale for this recipe.
In a batter bowl (one with a handle and a pouring spout) place one stick unsalted butter and melt in microwave until nearly melted. Cool, add baking soda (if using), baking powder, salt, milk, egg yolks; stir.
Add flour and beat briefly with a hand mixer or whisk. Stir in vanilla.
Using the whisk attachment of an electric mixer, beat the egg whites, gradually adding the sugar until soft, foamy stiff peaks form (not dry). Fold into batter and bake in waffle iron about 4 minutes or until steaming stops and waffles are golden brown.
