Warm milk and melted butter go into the batter the night before, along with instant yeast, flour, sugar, and salt — the whole thing takes about ten minutes to mix and then sits in the fridge overnight. By morning the batter is bubbly and slightly tangy, with a depth of flavor that same-day baking powder batters never develop. Two eggs and a teaspoon of vanilla stir in right before cooking. The result is a waffle with a genuinely crisp shell that holds up under maple syrup without turning soggy.
