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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the beans
Pick over the beans and soak them in cold water overnight.
Par‑boil the beans with the salt pork for one hour.
Drain off some of the water.
Season and bake
Add the sugar, salt, tomatoes, and vinegar to the beans.
Place the mixture in a baking pan and top with sliced pork.
Bake for 2.5 hours at 350°F (175°C).

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 soaking and par-boiling.
- Salt pork
- Adds fat and savory flavor that seasons the beans as they cook.
- Canned tomatoes
- Add acidity and moisture to the sauce around the beans.
- Brown sugar or molasses
- Adds sweetness and helps the beans brown during baking.
- Vinegar
- Adds acidity that balances the sweetness of the sugar.
The step that matters
Par-boil the beans with the salt pork for one hour. Beans must be cooked enough before baking, because acidic ingredients added later can slow softening. Cooking them first ensures they become tender in the oven.
Swap the tomato
How well each one fits the dish's main ingredients (beans, pork, sugar, vinegar):
- Mustardfits better
- Capsicumfits better
- Lettucefits about as well
- Tomatothe original
Fit is the average pairing score against beans, pork, sugar, vinegar. Candidates are from the same food group and used in at least 100 recipes.
