Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cream Puffs
Ingredients
Directions
The book says “a moderate oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux dough
In a saucepan, bring 1 cup of water to a boil and stir in ½ cup of butter until melted.
Remove from heat and quickly stir in 1 cup of flour until combined.
Allow to cool slightly, then stir in 3 beaten eggs until smooth.
Drop spoonfuls of the mixture onto greased baking pans.
Bake
Bake at 400°F (200°C) for 25 minutes.
Make the cream filling
For the cream filling, combine 1 cup of milk and ½ cup of sugar in a saucepan and bring to a boil.
Dissolve 1 heaping tablespoon of cornstarch in a little milk and add to the boiling mixture along with 1 egg.
Cook until thickened, then stir in 1 teaspoon of vanilla, the grated rind, and juice of 2 lemons.
Let the filling cool before using.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Set the puffs' structure and add moisture, helping the dough puff and hold its shape.
- Flour
- Gives the dough its structure once cooked in the water and butter base.
- Butter
- Adds fat and richness, tenderizing the dough and adding flavor.
- Cornstarch
- Thickens the cream filling as it cooks in the boiling milk.
- Milk
- Forms the liquid base of the cream filling, adding richness.
- Sugar
- Sweetens the cream filling and balances the lemon's acidity.
The step that matters
Bake the dough without opening the oven. Choux dough puffs because steam from its water and butter expands the batter quickly in the oven. Opening the door early lets that steam escape and the puffs may collapse or stay flat.

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