Browned Butter Seltzer Waffles

These waffles are airy and crisp thanks to dual leavening: baking powder and the carbonation of seltzer water. Make sure the can of seltzer is cold, as the liquid is fizzier chilled than at room temperature. We also cut the flour with a little cornstarch to help keep the texture light and tender. As a flavor booster, the butter is browned—the caramelized milk solids bring toasty, nutty notes to the batter. A final word of advice for achieving superior crispness: bake the waffles past the point of blond. Aim for richly browned. We prefer to use the highest (darkest) setting on our machine, however yours will almost certainly be different. It goes without saying—serve the waffles warm with butter and pure maple syrup.
