Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the thick batter together as it cooks.
- Sweet milk
- Adds moisture and liquid that hydrates the flour and forms the batter.
- Eggs
- Add structure and richness, helping the waffles set and hold together.
- Compressed yeast
- Produces gas that leavens the batter, giving the waffles a lighter texture.
- Butter
- Adds fat for flavor and a tender crumb, and helps browning on the iron.
The step that matters
Let the milk cool. Milk that is still hot can kill the yeast, so the batter will not rise properly. Letting it cool to lukewarm keeps the yeast active for leavening.
