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 ↓
Curried Beans with Tomato
Ingredients
Directions
Prepare the beans
Pick over and wash the pink beans, then place them in a pot with cold water.
Heat slowly until boiling, then add baking soda and boil for 15 minutes.
Drain the beans and return them to the pot with plenty of boiling water, then cook for another 10 minutes, then drain and rinse thoroughly.
Make the curry and finish
Peel and chop the apple (or orange) and onion.
Fry the apple and onion in oil until soft.
Add curry powder and salt to taste, then stir in the tomatoes.
Combine the mixture with the beans and cook for a few more minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pink beans
- Form the bulk of the dish and, once cooked, give it a soft, hearty texture.
- Baking soda
- Raises the pot's alkalinity, helping the beans soften during boiling.
- Apple or orange
- Adds sweetness and fruity acidity that balance the curry spice.
- Onion
- Softens and builds a savoury base of flavour when fried in oil.
- Tomatoes
- Add acidity, moisture and body that bind the curry into a sauce.
The step that matters
Boiling the beans with baking soda. Baking soda raises the pH of the cooking water, which helps the beans' skins and cell walls soften. Boiling them for the full time and then draining and rinsing removes the compounds that cause gas and bitterness, so the beans end up tender rather than tough or harsh.
Swap the apple
How well each one fits the dish's main ingredients (beans, onion, tomato):
- Avocadofits better
- Limefits better
- Cherryfits better
- Applethe original
Fit is the average pairing score against beans, onion, tomato. Candidates are from the same food group and used in at least 100 recipes.
