Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs add structure and richness, helping the waffles hold together and brown.
- Baking powder
- Releases gas when activated by the acid in the sour milk, helping the waffles rise and turn light.
- Sour milk
- Its acidity activates the baking powder and adds a tangy flavour.
- Flour
- Provides the structure that sets the batter as it cooks in the iron.
- Sweet cream
- Adds fat and richness, giving a tender texture and softer crumb.
The step that matters
Fold the beaten eggs in gently. Beaten eggs hold air that helps the waffles rise and stay light. Overmixing after adding them knocks out that air and can make the waffles dense and tough.
