Why it works: Peanut and onion match in chemistry and in kitchens. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,043 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Kidney-bean 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
Cook the beans as in the previous recipe and sift through a colander.
In a bowl, combine the sifted beans, sifted peanuts, zwieola, salt, sage, and grated onion if desired. Mix all the ingredients together.
If the mixture is too dry, add a little nut milk.
Bake
Transfer the mixture to an oiled baking dish.
Bake at 350°F (175°C) until nicely browned.
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
- Kidney beans
- Provide the bulk and body that hold the roast together.
- Peanuts
- Add protein-rich bulk and a rich, nutty flavor and texture.
- Zwieola
- Acts as a binder that helps the mixture hold its shape while baking.
Swap the sage
The recipe marks sage as optional. How well each one fits the dish's main ingredients (kidney beans, peanut, onion, milk):
- Garlicfits better
- Cuminfits better
- Corianderfits better
- Sagethe original
Fit is the average pairing score against kidney beans, peanut, onion, milk. 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.
