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 ↓
Baked Beans with Tomato Sauce
Ingredients
Directions
Prepare the beans
Wash the beans in cold water.
Pour boiling water with a tiny pinch of baking soda over the beans.
Simmer on the back of the stove until half done, leaving just enough water to cover them.
Season and bake
Add canned tomatoes, sugar, celery salt, coarse sea salt, cayenne pepper, and prepared mustard.
Place bacon and onion slices in the bottom of a casserole or baking dish.
Bake until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup beans or white kidney beans
- Provide the bulk of the dish, becoming tender and creamy as they cook slowly.
- Canned tomatoes
- Add acidity and moisture that thicken into a rich, saucy base.
- Sugar
- Adds sweetness that balances the acidity of the tomatoes and mustard.
- Prepared mustard
- Adds sharp tang and aroma that cut through the sweetness.
- Bacon
- Adds fat and smoky, savory flavor that seasons the beans as they bake.
- Onion
- Adds savory aroma and sweetness that deepens during baking.
The step that matters
Simmer until half done, keeping just enough water to cover. Beans cooked in too little liquid can scorch or cook unevenly, while the tomatoes added later need the beans to be partly tender so they finish softening in the oven rather than staying firm.
Swap the onion
How well each one fits the dish's main ingredients (beans, tomato, sugar, celery, pepper, mustard):

- Onionthe original
Fit is the average pairing score against beans, tomato, sugar, celery, pepper, mustard. Candidates are from the same food group and used in at least 100 recipes.
