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.
Make the cake
Preheat the oven to 350°F (175°C).
Cream together the butter and sugar until light and fluffy.
Add the flour, milk, eggs, lemon extract, and baking powder. Mix until smooth.
Pour the batter into jelly pans and bake until golden.
Make the custard
For the custard, heat 1 pint of milk in a saucepan.
In a bowl, whisk together 2 eggs, ½ cup sugar, and 1 tablespoon cornstarch.
Slowly add the hot milk to the egg mixture, stirring constantly.
Return the mixture to the saucepan and cook until thickened.
Stir in the butter until melted and smooth.
Assemble
Let the custard cool, then spread it between the baked cakes.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, and adds richness and tenderness to the cake.
- Eggs
- Add structure and richness to the batter, and thicken the custard when heated.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise and become light.
- Cornstarch
- Thickens the custard as it heats with the milk.
The step that matters
Cooking the custard after adding the hot milk. Stirring constantly keeps the eggs from scrambling when the hot milk is added. Cooking until thickened lets the starch swell and set the custard into a smooth filling.
Swap the lemon

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