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 ↓
Cream Cakes
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the choux batter
Bring the boiling water to a simmer in a pan and add the butter until melted.
Stir in the flour and let the mixture boil for one minute, stirring constantly.
Cool the mixture while stirring occasionally.
Once cool, add the beaten eggs and baking soda.
Drop spoonfuls of the batter onto a buttered baking sheet, spaced apart.
Bake at 400°F (200°C) for about 15 minutes; do not remove until fully baked to prevent collapsing.
Make the cream
For the cream, mix a portion of the milk with the flour until smooth.
Beat the eggs and combine with sugar and the remaining milk.
Heat the mixture, stirring occasionally, until it boils.
Quickly stir in the flour mixture until thickened.
Remove from heat and add lemon extract.
Assemble and serve
Once cooled, cut the cakes and fill them with the cream.

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
- Melts into the boiling water to add fat and richness to the batter.
- Flour
- Starch that thickens the cooked batter and sets the structure of the cakes and cream.
- Eggs
- Add structure and richness to the batter and help thicken the cream as they set.
- Baking soda
- Helps the batter rise and lighten during baking.
- Milk
- Provides liquid that thickens with flour and eggs to form the cream filling.
- Sugar
- Adds sweetness to the cream filling.
The step that matters
Bake until fully set. Removing the cakes before they are fully baked can make them collapse, because the starch and egg structure need time in the oven to firm up and hold their shape as they cool.

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