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 ↓

Ingredients
Directions
The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Rub the butter into the flour, then add the sugar and mixed peel.
Mix and bake
Dissolve the baking soda in the milk, let it cool, then mix it with the flour mixture.
Drop in the egg yolks and egg whites, and mix thoroughly.
Drop spoonfuls of the mixture onto a baking sheet and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Coats flour particles to keep the buns tender and rich.
- Flour
- Provides the structure that holds the buns together as they bake.
- Sugar
- Adds sweetness and helps the buns brown in the oven.
- Baking soda
- Releases carbon dioxide gas to lighten the mixture and aid browning.
- Egg yolks
- Add richness and fat, and help bind the mixture.
- Egg whites
- Add moisture and help set the structure as the buns bake.
The step that matters
Let the baking soda mixture cool before combining. Baking soda begins releasing gas as soon as it is dissolved in liquid. If the mixture is still warm, the gas forms faster and the lift may fade before the buns reach the oven, so letting it cool keeps the rise steady during baking.
