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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream together the sugar and butter.
Add the egg yolks and lemon juice, mixing well.
Dissolve the baking soda in a little water and add it to the mixture.
Stir in the sweet milk and flour until combined.
Fold in the beaten egg whites gently.
Bake
Pour the batter into patty tins.
Bake for about 20-25 minutes or until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks enrich the batter and whites, beaten and folded in, add lift and a light crumb.
- Baking soda
- Reacts with the acidic lemon juice to release gas, helping the cupcakes rise.
- Flour
- Provides the structure that sets the batter as it bakes.
- Butter
- Adds fat for tenderness and richness in the crumb.
- Lemon juice
- Adds acidity for bright flavor and reacts with the baking soda to aid rising.
- Sugar
- Sweetens the cupcakes and helps browning as they bake.
The step that matters
Fold in the beaten egg whites gently. Beaten whites hold air that gives lift. Stirring them vigorously deflates the foam, leaving dense cupcakes with less rise.
