Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites whipped to stiff peaks add lift and an airy, light structure to the batter.
- Baking soda
- Reacts with the acid in the sour milk to produce gas that helps the waffles rise.
- Cream of tartar
- Acidifies the sour milk mixture, activating the baking soda for lift and a tender crumb.
- Sour milk
- Its acidity reacts with the baking soda, adding tang and helping the waffles rise.
- Melted butter
- Adds fat for richness, tenderness, and golden browning in the waffle iron.
- Flour
- Provides the starch and gluten structure that sets the batter into a waffle.
The step that matters
Folding in the beaten egg whites. Whites hold air only if they are stiff and folded in gently. Stirring vigorously deflates them, which leaves the waffles dense instead of light.
