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 ↓
Lemon Cheese Cake
Ingredients
Directions
Make the batter
In a bowl, mix the grated lemon rind, lemon juice, egg yolks, and butter until well combined.
Add the sugar and mix until smooth.
In a separate bowl, beat the egg whites until stiff peaks form.
Fold the egg whites into the lemon mixture gently.
Incorporate the baking powder and sweet milk, then gradually add flour until the batter reaches a thick consistency.
Make the filling and bake
Cook the mixture on the stove until it thickens like sponge, being careful not to burn it.
Use this mixture as a jelly between cake layers.
Bake it as a square cake and spread the mixture on top, cutting it into diamond shapes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to stiff peaks, they add airy lift to the batter.
- Egg yolks
- Add richness and help bind the batter together.
- Butter
- Adds fat for a tender crumb and rich flavour.
- Sugar
- Adds sweetness and helps the mixture become smooth.
- Baking powder
- Releases gas during baking so the cake rises.
- Flour
- Provides the structure that sets the batter into a cake.
The step that matters
Cooking the mixture on the stove. Heat thickens the mixture as it cooks, but it can scorch on the bottom of the pan and turn bitter. Stirring constantly over gentle heat keeps it smooth and prevents burning.
