Buttermilk waffles that stay crisp

A waffle is not a pancake cooked in a grid. It needs more fat, so the surface fries against the iron, and it needs to stay in there long enough for the steam to leave. Open the lid early and you tear an uncooked batter in half. Four minutes, then look.

245 g of buttermilk is one cup. The acid wakes the baking soda, which is why the crumb is tender instead of bready. No buttermilk? Use the ratio on the buttermilk substitutes page and keep the soda. Milk alone, with the soda still in, tastes soapy. The buttermilk chart is the weight if your jug is metric and the recipe you started from was in cups.

Batter

190 g of all-purpose flour is about 1 1/2 cups plus a tablespoon, spooned. Scooping packs in extra flour and the waffle goes dry. The flour chart is the check. Stir until the dry streaks are gone and stop. A smooth, elastic batter means you built gluten, and the waffle will be tough even when it looks crisp.

The butter is 60 g, melted and cooled. Hot butter scrambles the egg when you whisk them together. 60 g is about 4 tablespoons, half a stick plus a bit. The butter chart covers a 250 g block that does not divide into sticks.

The iron

Heat it fully before the first pour. A cold iron makes a pale, steamy waffle and sets you up to undercook the rest. Grease sparingly. A pool of oil fries the edges black. Pour enough batter to spread when the lid closes, not so much that it pours out the sides.

When the steam coming from the iron slows to a wisp and the waffle is a deep gold, it is done. Pale gold will soften the minute it hits a plate. Set finished waffles on a rack, not a stack. A stack traps steam and undoes the crisp you waited for.

Serve with butter and maple syrup. Leftover waffles freeze well and reheat in a toaster.
