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
- Flour
- Forms the structure of the batter once it is hydrated and rested.
- Eggs
- Add structure and richness, helping the waffles hold together and brown.
- Yeast
- Ferments the sponge overnight, producing gas that leavens and gives flavour to the batter.
- Butter
- Adds fat for tenderness and golden browning on the waffle irons.
The step that matters
Cook quickly on very hot, greased irons. Sugars and proteins in the batter brown and can scorch quickly at high heat. Irons that are very hot and well greased set the outside fast, while a quick cook keeps the interior moist and prevents burnt patches.
