Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Produces gas as it ferments, leavening the batter so the waffles rise and turn light.
- Egg whites
- Beaten air folded in gives the waffles a light, airy structure.
- Egg yolks
- Add richness and help bind the batter for a tender crumb.
- All-purpose flour
- Forms the gluten network that gives the waffles their structure.
- Butter
- Adds fat for flavor and a tender texture, and helps browning in the iron.
- Sweet milk
- Provides the liquid that hydrates the flour and forms the batter.
The step that matters
Folding in the beaten egg whites gently. Deflating the whites by vigorous stirring loses the air bubbles that give a light, soft texture. Gentle folding keeps the batter airy so it rises well in the iron.
