Why it works: Butter and milk 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 ↓
Soft Waffles
Ingredients
Directions
Make the batter
Sift together the flour, sugar, baking powder, and salt, then rub in the butter.
Add the beaten eggs and mix with the milk to form a consistent batter.
Cook and serve
Preheat the waffle iron and grease it each time.
Pour the batter until two-thirds full, close the iron, and cook until brown.
Turn the waffle iron over and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the starch and gluten network that gives the waffles their structure.
- Eggs
- Add structure and richness, and help bind the batter together.
- Baking powder
- Releases gas when heated, making the batter rise and become light.
- Butter
- Adds fat that tenderises the crumb and carries flavour.
- Milk
- Adds moisture and liquid to hydrate the flour and set the batter's consistency.
- Sugar
- Adds sweetness and helps the surface brown during cooking.
The step that matters
Pouring the batter two-thirds full. Baking powder gives off gas as the waffle cooks, so the batter expands. Leaving room for this rise keeps the batter from overflowing and helps the waffle cook evenly.
