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 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
In a bowl, combine the walnuts, bread crumbs, onion, parsley, and seasoning. Mix well. If the mixture is too dry, add a little Marmite.
Shape and bake
Form the mixture into a loaf shape and spread the nut butter on top.
Bake in a moderate oven at 350°F (175°C) until heated through.
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.

- Provide the bulk and a rich, nutty body that holds the loaf together.
- Bread crumbs
- Absorb moisture and add binding so the loaf keeps its shape.
- Onion
- Adds savoury sweetness and moisture to the mixture.
- Nut butter
- Adds fat and richness, helping the top brown and the loaf stay moist.
