Sift 3 cups of flour with 1½ teaspoonfuls of baking-powder and ½ teaspoonful of salt. Beat the yolks of 3 eggs; add a tablespoonful of melted butter and 2 cups of warm milk. Add the beaten whites and stir in the flour, making a light batter. Grease the waffle irons and fill with the batter. Bake until a delicate brown. Remove to a hot dish. Serve hot with powdered sugar on top.
A plain, unsweetened waffle batter meant for a stovetop cast-iron waffle iron. A few of the instructions read oddly to modern eyes, and the order of mixing is worth correcting.
- Fix the mixing orderAs written, the beaten whites go in before the flour, which knocks the air out of them while you beat in three cups of dry flour. Combine yolks, butter and milk with the sifted dry ingredients first, then fold the whites into the finished batter last with a light hand.
- The irons are stovetopA 1900s waffle iron is hinged cast iron set over a burner and flipped partway through cooking. An electric waffle iron needs no greasing if non-stick, and no flipping unless it is a rotating model.
- "Delicate brown" in timeRoughly 3 to 5 minutes in a modern electric iron at medium-high; the steam pouring from the seam slowing to a trickle is the reliable signal, not the clock.
- Warm milk, not hotWarming the milk presumably keeps the melted butter from seizing into flecks. Blood temperature is enough. Milk hot enough to start cooking the yolks will give you a lumpy batter.
- Baking powder of the periodEarly-1900s baking powder was often single-acting, so batters were cooked promptly. Modern double-acting powder gives you more leeway, but this batter is still best used within about twenty minutes of folding in the whites.
- Fill sparingly"Fill with the batter" overfills a modern iron. Use enough to cover about two-thirds of the grid and let the lid spread it; the batter expands more than it looks.
- Yield and servingMakes about eight 7-inch waffles. With no sugar in the batter, the powdered sugar on top is doing all the sweetening — syrup, jam or fruit works equally well.
- Keeping them hotThe "hot dish" of the original means a warmed platter. Waffles stacked on a plate steam themselves soggy; hold them in a single layer on a rack in a 200F oven instead.
Waffles were not French in origin — the hinged iron and the batter cooked between plates are documented across medieval northern Europe, and the Low Countries and Germany have at least as strong a claim. What makes this one "French" in a book of national dishes is hard to say with any confidence. Day-a-year collections like this one leaned on such shorthand, giving each date a country and letting a single characteristic method stand in for a cuisine. The unsweetened batter is a reminder that a waffle need not be a sweet at all, which is why the sugar arrives at the table rather than in the bowl.
