The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and richness, setting the waffle as it cooks.
- Butter
- Adds fat for tenderness and flavor, and helps browning.
- Baking powder
- Releases gas during cooking so the waffles rise and turn light.
- Flour
- Forms the main structure that sets the batter into a waffle.
- Sweet milk
- Provides liquid to hydrate the flour and carry the batter's moisture.
The step that matters
Preheat the waffle iron before pouring the batter. A hot iron starts setting the outside of the batter immediately, which creates a crisp golden crust and keeps the waffle from sticking or steaming soft.
