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 paste
In a saucepan, bring the boiling water and butter to a boil.
Stir in the flour and let it cool.
Add the beaten eggs one at a time, mixing well after each addition.
Drop spoonfuls of the mixture into muffin rings.
Bake
Bake at 400°F (200°C) for 30 minutes.
Make the custard
Boil the milk.
Mix flour, sugar, and eggs in a bowl.
Add this mixture to the boiling milk and cook for 3 minutes.
Fill and serve
Cut a small hole in the top of each puff.
Fill with custard.
Replace the piece of crust.

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
- Beaten into the paste to add structure and help the puffs rise and set.
- Butter
- Adds fat and richness to the paste, giving a tender texture.
- Flour
- Forms the structure of the paste and thickens the custard.
- Milk
- Forms the liquid base of the custard, adding creaminess and body.
- Sugar
- Sweetens the custard and helps it brown lightly.
The step that matters
Add the beaten eggs one at a time, mixing well after each addition. Each egg must be fully absorbed before the next goes in, or the paste breaks and turns greasy. A smooth, glossy paste holds its shape and puffs up in the oven.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, flour, egg, milk, sugar):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
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.
