Waffles

Ingredients

Directions

Make the batter

  1. The night before, stir the flour into the sour or buttermilk and let it sit overnight.

  2. In the morning, beat the mixture for 10 minutes.

  3. Add the molasses or brown sugar, melted shortening, and well-beaten eggs.

  4. Dissolve the baking soda in a little warm water and add it to the mixture.

Cook and serve

  1. Preheat the waffle iron and grease it thoroughly.

  2. Pour a thin layer of batter into the hot waffle iron.

  3. Cook until one side is browned, then flip the iron to brown the other side.

  4. Serve hot with maple syrup.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Flour
Forms the structure of the batter that holds the waffle together once cooked.
Eggs
Add structure and richness, helping the waffles set and hold their shape.
Sour or buttermilk
Its acidity reacts with the baking soda to produce gas that lightens the batter.
Baking soda
Reacts with the acid in the sour milk or buttermilk to make the waffles rise and turn tender.
Shortening
Adds fat that gives tenderness and helps the waffles release and brown in the iron.

The step that matters

Dissolve the baking soda and add it to the batter. Baking soda must be fully dissolved so it reacts evenly with the acidic sour milk or buttermilk. Lumps leave pockets of unreacted soda and uneven rising and flavor.
