Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

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 paste
Boil the water in a pot.
Rub together the butter and sifted flour.
Stir the butter and flour mixture into the boiling water until it thickens.
Remove from heat and let cool.
Stir in the well-beaten eggs and baking soda.
Drop spoonfuls of the mixture onto buttered baking tins.
Make the cream
Beat the eggs to a froth, then mix in the sugar and flour.
Stir the mixture into the boiling milk until it thickens, then remove from heat and flavor with lemon or vanilla.
Let the cream cool before filling the puffs.
Bake and fill
Bake in a 400°F (200°C) oven until light brown.
Once baked, open one side of each puff and fill with mock cream.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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, setting the puffs as they bake and thickening the cream.
- Flour
- Provides the structure that holds the puffs and thickens the cream filling.
- Butter
- Adds fat and richness, contributing tenderness and flavor to the puffs.
- Milk
- Forms the base of the cream, adding moisture and richness as it thickens.
- Baking soda
- Helps the puffs rise and lighten during baking.
- Sugar
- Sweetens the cream filling and adds flavor.
The step that matters
Stir the butter and flour into the boiling water until it thickens. The flour must be fully mixed and cooked in the hot liquid so starch gelatinizes and forms a smooth paste. Undercooked or lumpy paste gives dense puffs that may not hold their shape or rise well.
