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 Cream 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.
Make the batter
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar.
Add the sweet milk and mix well.
In a separate bowl combine the flour and baking powder.
Gradually add the dry ingredients to the wet mixture.
Fold in the beaten egg yolks.
Beat the egg whites until stiff and fold them into the batter.
Pour the batter into a greased cake pan and bake until golden.
Make the lemon filling
Combine 1 cup sugar, 2 teaspoons butter, 2 eggs, grated rind and juice of 2 lemons in a saucepan.
Cook over medium heat until it thickens to a jelly‑like consistency.
Assemble and serve
Spread the filling between the cake layers and dust powdered sugar on top.

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 stiff, lighten it and help the cake rise and hold its structure.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb to the cake.
- Flour
- Forms the cake's structure once mixed with the liquid and set by heat.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Sugar
- Sweetens the cake and helps brown it, and in the filling it thickens with the lemon juice.
- Lemons
- Juice adds acidity and bright flavour, and the rind adds aroma to the filling.
The step that matters
Cooking the lemon filling over medium heat. The filling thickens as egg proteins set and sugar and juice combine. Heat that is too high can scramble the eggs, while too little heat leaves it runny.
Swap the lemon
