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 quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux batter
Bring 1 cup of water to a boil in a saucepan and melt in ½ cup of butter.
Stir in 1 cup of all-purpose flour until smooth.
Remove from heat, let cool, then stir in 3 eggs one at a time.
Drop spoonfuls of the batter onto baking sheets and bake for 20 minutes at 400°F (200°C).
Make the custard
Boil 1 cup of milk.
Beat 2 egg yolks with 4 tablespoons of powdered sugar until stiff.
Pour the boiling milk over the egg mixture while stirring continuously.
Mix 2 tablespoons of cornstarch with a little cold milk, add to the custard, and return to heat.
Stir until thick, then let cool and flavor with vanilla.
Assemble
Cut the tops off the puffs and spoon in the cream.

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 and richness, and help the puffs rise and set as they bake.
- Butter
- Adds fat and richness, and tenderness to the choux shell.
- All-purpose flour
- Forms the starch and gluten structure that holds the choux shell together.
- Milk
- Provides the liquid base of the custard, adding creaminess and body.
- Egg yolks
- Thicken the custard and add richness and smoothness.
- Cornstarch
- Thickens the custard so it sets firm and holds its shape.
The step that matters
Stir in the eggs one at a time after the batter cools. If the batter is too hot, the eggs scramble and the dough cannot hold the steam needed to puff. Adding eggs gradually lets the dough reach a smooth, thick consistency that expands 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.
