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 dough
Preheat the oven to 400°F (200°C).
In a saucepan, combine hot water and butter; bring to a boil.
Mix in the sifted flour and stir until it forms a paste.
Remove from heat and let cool slightly.
Stir in the eggs one at a time without beating, mixing for five minutes.
Bake
Drop tablespoonfuls of the mixture onto a buttered baking pan, leaving space between each.
Bake for 25 minutes, avoiding opening the oven door frequently.
Make the custard
For custard, whisk together 1 egg and ½ cup sugar.
Heat 1 cup milk in a double boiler until scalding hot.
Gradually pour the hot milk over the egg and sugar mixture, stirring constantly.
Return to heat, add 3 tablespoons flour mixed with a little milk, and cook until thick, being careful not to curdle.
Add vanilla and let cool before filling the cream puffs.
Fill and serve
Once cooled, cut a slit in each puff and fill with whipped cream or custard.

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
- Add structure to the dough and help it puff, and thicken the custard when cooked.
- Butter
- Adds fat and richness, tenderizing the dough.
- Flour
- Forms the paste's structure and thickens the custard.
- Hot water
- Turns to steam in the oven, helping the dough puff and hollow out.
- Sugar
- Adds sweetness to the custard.
- Milk
- Forms the liquid base of the custard, giving body and creaminess.
The step that matters
Cooking the custard without curdling. Egg proteins set when heated, so overheating or adding hot milk too quickly can scramble the eggs. Pouring the milk in gradually while stirring constantly and cooking gently keeps the custard smooth and thick.
Swap the vanilla
How well each one fits the dish's main ingredients (egg, butter, flour, milk, sugar):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against egg, butter, flour, milk, sugar. Candidates are from the same food group and used in at least 100 recipes.
