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 Croquettes
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 potato mixture
Boil the potatoes and mash them through a sieve or beat with two forks.
While hot, mix in the butter, hot milk, pepper, and salt until smooth.
Add the eggs and continue beating until well combined.
Let the mixture cool on a dish.
Shape and cook
Flour your hands and shape the mixture into croquettes.
Roll each croquette in the beaten egg, then in breadcrumbs.
Fry in plenty of boiling fat until golden brown.
Alternatively, shape into flat cakes, place on a greased baking sheet, score the tops, brush with egg, and bake in a 400°F (200°C) oven for a few minutes.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the croquette and give it a soft, starchy body.
- Butter
- Adds fat for richness and a smoother, more tender mash.
- Hot milk
- Adds moisture so the mashed potato becomes smooth and pliable for shaping.
- Eggs
- Bind the mixture so it holds its shape, and the beaten egg coating helps breadcrumbs stick.
- Breadcrumbs
- Form a crisp, golden outer crust when fried or baked.
The step that matters
Let the mixture cool before shaping. Warm potato mash is soft and sticky, so it tears and sticks to the hands. Cooling firms the starch so the croquettes keep their shape through coating and frying.
Swap the potato
How well each one fits the dish's main ingredients (butter, milk, pepper, egg):
- Capsicumfits about as well
- Potatothe original
- Asparagusfits about as well
- Chivefits less well
Fit is the average pairing score against butter, milk, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
