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 ↓
Bean Soup
Ingredients
Directions
Prepare the beans
Soak the beans in cold water overnight.
In the morning, drain and wash the beans.
Simmer the soup
Put the beans into a soup kettle with the beef stock, removing all grease.
Bring to a boil and then simmer slowly for 4 hours, until the beans are soft.
Finish and serve
Before serving, add the can of tomatoes and season with salt and pepper.
Strain the soup through a wire sieve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beans
- Provide the main body and starch that thickens the soup as they soften.
- Beef stock
- Supplies the liquid and savoury flavour that the beans cook in.
- Tomatoes
- Add acidity and a fresh, tangy flavour to the finished soup.
The step that matters
Simmering the beans for 4 hours. Beans must cook long enough to become fully soft; a fast boil can leave them firm or split them. A gentle simmer lets starches gelatinize evenly and keeps the soup clear.
