Why it works: Onion and garlic match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 29,030 recipes mention both. Both carry furaneol, which smells caramel, strawberry. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Cook the beans
Put the drained beans and hock in a very large pan, cover with cold water, bring gradually to a boil, and leave to simmer while you prepare the other ingredients.
Heat the olive oil in a frying pan, gently fry the onion, garlic, and chili with allspice and lemon rind, stirring occasionally, until the onions are translucent.
Add the fried mixture to the beans, simmer for 2 hours until the beans are tender, then add sugar, lemon juice, and tomato paste, and cook for another 30 minutes.
Add salt if necessary.
Finish the soup
Remove the hock, pick off any meat, and if a smooth soup is desired, process the mixture in batches and return it with the meat to the pan.
If a rougher texture is preferred, crush the mixture with a potato masher; if it is too thick, add more water and bring back to a boil for a minute or two.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried black beans
- Provide the main body and thickness of the soup as they cook down.
- Ham hocks
- Add smoky, savory depth to the broth as they simmer with the beans.
- Onions
- Soften and sweeten as they fry, building the base flavor of the soup.
- Tomato paste
- Adds concentrated acidity and deeper color to the finished soup.
- Creme fraiche or sour cream
- Adds richness and a cooling tang to balance the spiced soup.
The step that matters
Simmering the beans until tender. Dried beans must cook long enough to soften fully; adding acidic ingredients such as tomato paste and lemon juice only after the beans are tender helps prevent them from toughening and staying firm.

Fit is the average pairing score against beans, ham, olive, onion, garlic, pepper, sugar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
