Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Hoppin' John with Ham Hocks
Ingredients
Directions
Cook the ham hocks
Combine ham hocks, onion, salt, crushed red pepper, and water in a large saucepan.
Bring to a boil, cover, and simmer 1¼ hours, or until ham is tender.
Remove ham hocks from saucepan.
Add water to the liquid left in the saucepan to measure 3½ cups, if necessary.
Prepare the peas
Wash black‑eyed peas.
Combine black‑eyed peas and 6 cups water; bring to a boil and boil 2 minutes.
Remove from heat, cover, and let stand 1 hour.
Drain black‑eyed peas; discard soaking liquid.
Finish and season
Cut meat into small pieces, discarding bone and rind.
Combine ham, black‑eyed peas, and rice in a large saucepan; bring mixture to a boil.
Reduce heat, cover, and simmer 20 to 25 minutes, or until black‑eyed peas and rice are tender and liquid is absorbed.
Season to taste with salt and black pepper.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ham hocks
- Release smoky, savory flavor and gelatin into the cooking liquid as they simmer.
- Black-eyed peas
- Hold their shape while becoming tender, giving the dish its creamy, earthy body.
- Rice
- Absorbs the cooking liquid and adds starch, turning the dish fluffy and filling.
- Onion
- Adds aromatic sweetness and depth to the simmering broth.
The step that matters
Drain the peas and discard the soaking liquid. The soaking water carries compounds that cause gas and off flavors, and the liquid must be replaced with fresh measured water so the rice cooks properly.
Swap the onion
How well each one fits the dish's main ingredients (ham, pepper, rice):
- Capsicumfits better
- Carrotfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against ham, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
