Why it works: Ham and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,536 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓
Ham and Pea Soup
Ingredients
Directions
Make the soup
Place the ham bone in a large pot with 3 quarts of cold water and 1 pint of dried peas.
Bring to a boil and simmer slowly for 6 hours, until the peas are tender.
Strain and serve
Use a potato masher to rub the peas through a sieve into a bowl.
Return the strained soup to the pot, discarding the ham bone.
Season the soup with salt and pepper, then heat it through.
Serve with toast cut into half-inch dice or small fried bread cubes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Break down during long simmering to thicken the soup and give it body.
- Ham bone
- Releases flavor into the water during long simmering, seasoning the soup.
The step that matters
Simmer slowly until the peas are tender. A gentle simmer lets the peas soften fully without breaking apart too early or scorching on the bottom of the pot. Full softening is what allows them to be pressed through a sieve smoothly.
Swap the peas
How well each one fits the dish's main ingredients (ham, pepper, bread):
- Peasthe original
- Lima beansfits about as well
- Beansfits about as well
- Chestnutfits less well
Fit is the average pairing score against ham, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
