Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the main structure that sets as the waffle cooks.
- Eggs
- Add richness and structure, and the whipped whites lighten the batter.
- Baking powder
- Releases gas during cooking, helping the waffles rise and become airy.
- Milk
- Supplies the liquid that hydrates the flour and forms the batter.
- Butter
- Adds fat for flavor and tenderness, and helps the surface brown.
The step that matters
Whip the batter lightly and quickly. Overmixing flour and liquid develops gluten, which makes waffles tough and dense. A brief, gentle mix keeps them tender.
