Why it works: Lima beans and walnut work together. They rank in the top 12% of all ingredient pairs, and cooks put them together in 15 recipes. Both carry 2,3,5-trimethylpyrazine, which smells cocoa, roasted. The science ↓
Lima Bean Soup
Ingredients
Directions
Prepare the beans
If using green lima beans, peel them.
If using dry lima beans, cook them until the skins loosen, then remove the skins.
Cook and serve
Boil the beans in 1 quart of water until they are very soft and can be mashed easily.
Add ¼ cup butter, salt, and pepper to taste.
Serve with crisp oyster crackers.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lima beans
- Form the body of the soup, becoming soft and thick when boiled and mashed.
- Butter
- Adds richness and a silky mouthfeel to the soup.
The step that matters
Boil the beans until very soft. Lima beans must be cooked fully to break down their starches and skins, so they mash smoothly into a creamy soup rather than leaving grainy or tough pieces.
Swap the lima beans
How well each one fits the dish's main ingredients (butter, walnut, pepper, oyster):
- Almondfits better
- Pistachiofits better
- Cashew nutfits better
- Lima beansthe original
Fit is the average pairing score against butter, walnut, pepper, oyster. Candidates are from the same food group and used in at least 100 recipes.
