Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cheese and Nut Roast
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the onion
Cook the onion in the butter with a little water until tender.
Mix and moisten
Mix the cheese, walnuts, bread crumbs, lemon juice, salt, and pepper.
Moisten the mixture with the water from cooking the onion.
Bake
Pour into a shallow dish.
Brown in the oven at 400°F (200°C).
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
- Cheese
- Adds richness, savory flavor, and helps bind the roast together as it melts.
- English walnuts
- Provide body and a firm, chewy texture that gives the roast its substance.
- Bread crumbs
- Absorb moisture and give the mixture structure so it holds its shape.
- Butter
- Cooks the onion gently and adds fat for flavor and tenderness.
The step that matters
Moistening the mixture. Too little liquid leaves the bread crumbs dry and the roast crumbly, while too much makes it soggy and slow to set. Add the onion water gradually so the crumbs absorb it evenly and the mixture holds together when shaped and baked.
Swap the onion
How well each one fits the dish's main ingredients (cheese, walnut, bread, butter, lemon, pepper):
- Capsicumfits better

- Asparagusfits better
- Onionthe original
Fit is the average pairing score against cheese, walnut, bread, butter, lemon, pepper. Candidates are from the same food group and used in at least 100 recipes.
