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 ↓
Potato 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.
Prepare the mixture
Dissolve the sugar in the new milk.
Rub the boiled potato to a fine powder and mix with the sugar and milk.
Add the grated lemon rind and egg yolks, then beat for 10 minutes.
Fold in the beaten egg whites gently.
Bake and serve
Butter five small tin molds and fill each with a fifth of the mixture.
Bake in a 400°F (200°C) oven for about 18 minutes.
Serve immediately with sifted sugar on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and emulsify the batter, giving a tender, custard-like crumb.
- Egg whites
- Whipped and folded in, they trap air that lifts the puffs as they bake.
- Mealy potato
- Its fine starch gives a light, soft body and moisture to the batter.
- Loaf sugar
- Sweetens the batter and helps the puffs brown lightly in the oven.
- New milk
- Supplies moisture that hydrates the potato and sugar into a smooth batter.
The step that matters
Fold in the egg whites gently. Whipped egg whites hold air that makes the puffs rise. Stirring vigorously knocks that air out, so the puffs bake flat and dense.
Swap the potato
How well each one fits the dish's main ingredients (sugar, milk, lemon, egg, butter):

Fit is the average pairing score against sugar, milk, lemon, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
