Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the main structure that holds the waffle together as it cooks.
- Baking powder
- Releases gas when heated, helping the waffles rise and turn light and airy.
- Eggs
- Add structure and richness, helping the batter set firm in the iron.
- Milk
- Hydrates the flour and gives the batter its pourable, tender texture.
- Melted butter
- Adds fat for flavor and a tender crumb, and helps the surface brown.
- Sugar
- Adds sweetness and helps the exterior take on golden browning.
The step that matters
Combine wet and dry ingredients until just mixed. Overmixing develops gluten in the flour, which can make waffles tough and dense. Stop once no dry streaks remain; small lumps are fine.
