Why it works: Bread and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
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 mixture
Grind the nuts until you have enough to fill 2 cups.
Mix the ground nuts with the bread crumbs.
Grate the onions, discarding tough pieces.
Mix the soft pulp and juice with the nut and crumb mixture to form a stiff paste.
If using tomatoes, skin and mash 2 tomatoes instead of onions, or use 1 onion and 1 tomato.
Bake
Grease a pie dish.
Fill the pie dish with the mixture.
Spread butter on top.
Bake at 400°F (200°C) until brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Absorb moisture and bind the nuts into a firm, sliceable mass.
- Ground nuts
- Provide the main body, fat and rich, toasty flavor of the roast.
- Onions
- Add moisture and savory flavor, softening during baking to keep the roast tender.
- Butter
- Adds fat and richness and helps the top brown in the oven.
The step that matters
Form a stiff paste. The mixture must be stiff enough to hold its shape; too much juice from the onion or tomato makes the roast soggy and crumbly once sliced. Bread crumbs soak up liquid, so the pulp should be added gradually and the paste checked before filling the dish.
Swap the nuts
How well each one fits the dish's main ingredients (bread, onion, butter):
- Lima beansfits better
- Beansfits better
- Peanutfits better
- Nutsthe original
Fit is the average pairing score against bread, onion, butter. Candidates are from the same food group and used in at least 100 recipes.
