Why it works: Butter and milk match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 81,222 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions

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 cakes together as they bake.
- Yeast
- Produces gas that makes the cakes rise and become airy.
- Egg
- Adds structure and richness, helping the cakes bind and set.
- Butter
- Adds fat for tenderness and flavour, and helps browning.
