Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the beans and place them in a large earthenware jar with the bacon or pork.
Peel the onion and add it to the jar.
Mix the water and treacle and add the pepper.
Pour the mixture over the beans.
Bake and serve
Cover the jar and bake in a slow oven at 300°F (150°C) for eight hours.
After baking, remove the beans from the jar.
Mix in the tomato puree.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the bulk of the dish and become tender during the long, slow bake.
- Bacon or pork
- Adds fat and savory flavor that seasons the beans as they cook.
- Treacle
- Adds dark sweetness and color to the sauce.
- Tomato puree
- Adds acidity, body and tomato flavor to the finished beans.
The step that matters
Long, slow baking. Dried beans need a long, gentle bake to soften fully and absorb the sauce. Cooking too hot can toughen the skins or split the beans before they become creamy inside.
Swap the onion
How well each one fits the dish's main ingredients (beans, pepper, pork, tomato):
- Capsicumfits better
- Potatofits better
- Okrafits better
- Onionthe original
Fit is the average pairing score against beans, pepper, pork, tomato. Candidates are from the same food group and used in at least 100 recipes.
