Can I make the batter ahead?
You can mix the dry ingredients ahead and keep them in a container. For the wet ingredients, you can whisk them together and refrigerate overnight. When you are ready, combine wet and dry and cook. Fully mixed batter can be made a few hours ahead, but it may lose some lift as it sits.
How spicy are these?
As written, they are mild to medium. You notice warmth more than heat. If cooking for kids or spice-sensitive folks, use the “mild” option in the ingredient list. If you want bolder heat, bump cayenne up slowly.
What if I do not have buttermilk?
In a pinch, make a quick stand-in (aka “soured milk”): add 2 tablespoons lemon juice or white vinegar to a measuring cup, then fill with milk to the 2-cup line. Stir and let sit 5 minutes. It will be thinner and less tangy than real buttermilk, but it still gets the job done and gives the baking soda enough acidity to work.
Why are my waffles sticking?
Most common causes: the iron was not fully preheated, you opened the lid too early, or the nonstick surface needs a light oiling. Preheat longer than you think, and wait until steam slows down before lifting the lid. If your iron is older, a quick brush of oil between batches can help.
Why are my waffles not crisp?
Usually one of three things: the iron was not hot enough, the waffles were pulled too early, or they were stacked (steam is the enemy of crunch). Cook until deeply golden, then cool on a wire rack. For a crowd, keep them in a 200°F oven on a rack, not on a plate.
How do I keep waffles warm for a crowd?
Set a wire rack on a sheet pan and keep waffles in a 200°F oven. Do not stack them, or they will steam and soften.
