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
Ingredients
Directions
Prepare the beans
Soak the beans for 2 to 3 hours until the skins are loose.
Rub the beans between your palms to remove the skins.
Rinse the beans with cold water and place them in a bean pot.
Assemble and bake
Add the chopped onion, tomato sauce, and chili sauce to the pot.
Bury the bacon in the beans.
Mix boiling water with mustard, salt, and molasses to cover the beans.
Keep the beans covered until the last hour of cooking.
In the last hour, lift the bacon to the top and brown it.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Form the main body of the dish and absorb the sauce as they cook.
- Molasses
- Adds dark sweetness and a deep, rich colour to the sauce.
- Bacon
- Adds savoury fat and flavour, and browns on top during the final hour.
- Tomato sauce
- Adds acidity and body to the sauce around the beans.
- Onion
- Adds savoury depth and aroma as it cooks into the sauce.
The step that matters
Keep the beans covered until the last hour of cooking. Covering holds in moisture so the beans cook through slowly without drying out, while the uncovered final hour lets the bacon brown.
Swap the onion
How well each one fits the dish's main ingredients (beans, mustard, molasses, tomato, sauce):
- Lettucefits better
- Horseradishfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against beans, mustard, molasses, tomato, sauce. Candidates are from the same food group and used in at least 100 recipes.
