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 ↓
Potato Puff
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 mixture
Stir melted butter into cold mashed potatoes until light.
Add beaten eggs, milk, and salt; beat thoroughly.
Pour the mixture into a buttered pudding dish.
Bake
Bake in a 400°F (200°C) oven until nicely browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Provides the bulk and soft body that the puff is built on.
- Eggs
- Set when heated, giving the puff its structure and holding it together.
- Butter
- Adds fat for richness and a tender crumb, and helps browning.
- Milk
- Adds moisture and loosens the mixture so it bakes softly.
The step that matters
Bake until nicely browned. Heat sets the beaten eggs into a firm structure and browns the surface. Underbaking leaves the centre wet and collapsed, while the browning shows the eggs have set.
Swap the potato
How well each one fits the dish's main ingredients (butter, egg, milk):
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
- Leekfits less well
Fit is the average pairing score against butter, egg, milk. Candidates are from the same food group and used in at least 100 recipes.
