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 ↓
Pancakes
Ingredients
Directions
Make the batter
Mix flour, milk, egg yolks, salt, and brandy to create a batter.
Cook and serve
Melt butter in a frying pan over medium heat.
Pour a large tablespoonful of batter into the pan.
Cook until the bottom is golden, then flip and cook the other side.
Sprinkle with powdered sugar, fold like a small omelet, and serve.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 pancake together as it cooks.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
- Egg yolks
- Add richness and help bind the batter for a tender texture.
- Butter
- Coats the pan and adds fat for browning and flavor.
The step that matters
Cook until the bottom is golden before flipping. Flipping too early can tear the thin pancake, while cooking until the underside is set and golden gives it enough structure to turn cleanly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
