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 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux paste
In a saucepan, combine hot water and butter. Bring to a boil.
Once boiling, mix in the sifted flour and remove from heat. Stir until a paste forms.
Let the mixture cool, then stir in the eggs one at a time without beating. Stir for five minutes.
Drop tablespoonfuls of the mixture onto a buttered baking pan, leaving space between each.
Bake and cool
Bake at 400°F (200°C) for 25 minutes, avoiding opening the oven door frequently.
Once cooled, cut a slit in each puff and fill with whipped cream or custard.
Make the custard
For the custard, stir together sugar and egg in a bowl.
Heat milk in a double boiler until scalding hot, then gradually pour it over the sugar and egg mixture, stirring constantly.
Return the mixture to the heat and add flour mixed with a little milk. Cook until thick, being careful not to let it curdle.
Add vanilla to taste, let cool, and then fill the cream puffs.

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
- Provide structure and richness, helping the paste puff and set as it bakes.
- Butter
- Adds fat and richness and helps the choux dough stay tender.
- Sifted flour
- Forms the paste's structure, which traps steam so the puffs rise hollow.
- Milk
- Gives the custard its body and creamy texture.
- Sugar
- Adds sweetness and helps thicken the custard with the egg.
The step that matters
Cook the custard without curdling. Egg proteins set when heated, so if the custard gets too hot or cooks too fast it can curdle. Gentle heat and constant stirring keep it smooth and thick.
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.
