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 ↓
White Cup Cake
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.
Prepare the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Whip in the lemon juice and grated lemon peel.
Gradually add the stiffened egg whites and flour alternately, mixing well.
Bake
Pour the batter into a loaf pan or layer pans.
Bake until a toothpick inserted in the center comes out clean.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cupcake a light, tender crumb.
- Egg whites
- Whipped stiff to add air and structure, helping the cake rise and hold its shape.
- All-purpose flour
- Provides the main structure that sets as the cake bakes.
- Sugar
- Creams with the butter to aerate the batter and adds sweetness and browning.
- Milk
- Adds moisture and helps the flour hydrate into a smooth batter.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
The step that matters
Gradually add the stiffened egg whites and flour alternately, mixing well.. Folding in the stiff whites gently keeps the air bubbles intact; overmixing after adding flour develops gluten and can make the cake tough and dense.
Swap the lemon

Fit is the average pairing score against butter, sugar, milk, egg, flour. Candidates are from the same food group and used in at least 100 recipes.
