Why it works: Milk and butter 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 hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Beat the eggs well in a bowl.
Mix all the ingredients together until smooth.
Pour the mixture into little cups, filling them half full.
Bake and serve
Bake for 20 minutes until the puffs are golden brown.
Turn out onto a flat dish, brush with a little melted butter, and dust with powdered sugar.

Flour and butter 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
- Provide structure and set the batter, while their moisture turns to steam that lifts the puffs.
- Flour
- Gives the batter body so it holds its shape around the rising steam.
- Milk
- Adds moisture and makes the batter pourable, helping it expand in the hot oven.
- Melted butter
- Adds fat and richness, and helps the finished puffs brown and taste savoury.
The step that matters
Bake for 20 minutes until the puffs are golden brown. The puffs rise from steam produced in a hot oven, so the oven must be fully preheated and the batter should not be opened early. Opening the door or underbaking can cause the puffs to collapse as they cool, and the browning shows the starch and proteins have set.
Swap the nutmeg
How well each one fits the dish's main ingredients (flour, egg, milk, butter):
- Nutmegthe original
- Cinnamonfits about as well
- Capersfits less well
- Parsleyfits less well
Fit is the average pairing score against flour, egg, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
