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 Puffs
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 puff batter
Preheat the oven to 400°F (200°C).
In a bowl, beat together 2 whole eggs, 1 cup sugar, and ½ cup butter until smooth.
Add 1 cup sweet milk, 2 teaspoons baking powder, and 2 cups flour. Mix well.
Spoon the batter onto a baking sheet and bake until golden.
Make the cream filling
While the puffs are baking, heat 1 pint of milk in a saucepan.
In another bowl, mix together 2 eggs, sugar, and flour, then add to the heated milk.
Cook the mixture until it thickens to a cream‑like consistency and flavor with lemon.
Assemble
Once the puffs are baked, split them while hot and fill 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
- Eggs
- Bind the batter and thicken the cream filling as they cook.
- Butter
- Adds fat and richness, giving the puffs a tender texture.
- Flour
- Provides the structure that holds the puffs and thickens the cream.
- Baking powder
- Releases gas in the oven so the puffs rise and open up.
- Milk
- Supplies liquid that moistens the batter and forms the cream base.
The step that matters
Bake the puffs until golden and split them while hot. Puffs need a fully baked, dry shell to hold their shape; under-baked shells collapse. Splitting them while hot lets steam escape so they do not turn soggy.

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