Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich and bind the batter, while beaten whites add air that lightens the waffles.
- Flour
- Provides the structure that holds the waffles together once the batter sets in the iron.
- Milk
- Adds moisture and liquid that hydrates the flour and gives the batter its pourable body.
- Baking soda
- Helps the batter rise and become light as gas forms within it.
- Butter
- Adds fat for richness, tender texture, and golden browning on the waffle surface.
The step that matters
Gently fold in the beaten egg whites. Egg whites hold air bubbles that lighten the batter. Vigorous stirring knocks that air out, leaving dense, flat waffles.
