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 hot oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the choux dough
In a kettle, combine butter and water, and bring to a boil.
Stir in the sifted flour and set aside to cool.
Add the eggs two at a time, mixing gently.
Drop spoonfuls of the mixture onto a baking sheet, spacing them about three inches apart.
Bake and fill
Bake in a moderate oven (350°F / 175°C) for about 20 minutes.
Once cooled, cut open the side of each puff with a sharp knife.
For the cream, mix sugar, cornstarch, and eggs in a pail.
Add milk and stir well, then place the pail in a kettle of boiling water.
Stir until thick, then cool and add vanilla extract to taste.

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 richness and fat for a tender crumb.
- Flour
- Starch and gluten form the structure that holds the puffs while they bake.
- Eggs
- Add structure as they set and provide moisture that steams the puffs up.
- Sugar
- Adds sweetness and helps the cream stay smooth and tender.
- Cornstarch
- Thickens the cream as it heats, giving it a firm, sliceable body.
- Milk
- Forms the liquid base of the cream, adding richness and body.
The step that matters
Stir the cream until thick over boiling water. Cornstarch needs to reach a boil in the mixture to fully thicken. Stirring keeps the eggs from scrambling against the hot pail, giving a smooth custard.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, flour, egg, sugar, milk):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, flour, egg, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
