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 gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and powdered sugar together.
Whip in the egg yolks, milk, and lemon peel.
Fold in the whipped egg whites and flour alternately.
Pour the mixture into small buttered tins or 'gem' pans.
Bake and serve
Bake until golden, then turn out while hot.
Serve with a sweet sauce.

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
- Prepared flour
- Provides the starch structure that sets the puffs once baked.
- Eggs
- Whipped whites trap air for lift, while yolks add richness and set the structure.
- Butter
- Adds fat for tenderness and a rich flavour.
- Powdered sugar
- Sweetens the batter and helps create a fine, even crumb when creamed with butter.
- Milk
- Adds moisture so the batter pours and bakes through evenly.
The step that matters
Fold in the whipped egg whites and flour alternately. Folding gently keeps the air in the whipped whites. Deflating them makes the puffs dense instead of light and airy.
