Why it works: Beans and rice match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 1,017 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Cajun Red Beans and Rice
6 people for 2-3 daysIngredients
Directions
Prepare the beans
Cover beans with water and let soak overnight.
Drain.
Simmer the ham hocks
Place ham hocks, celery, onions, bell peppers, bay leaves, and seasoning into a large saucepan with 10 cups water.
Cover and bring to boil.
Simmer until meat is fork tender, about an hour after boiling starts, stirring occasionally.
Remove ham hocks from pan and set aside.
Skim fat from pan and discard.
Cook the beans
Remove a significant fraction of liquid from pan.
Add drained beans.
Add back just enough liquid to cover beans.
Simmer beans until they just begin to break up and the liquid starts to become creamy, about 45 minutes.
Stir frequently.
Add back liquid as needed to keep beans covered.
If beans begin to scorch, do not stir; transfer mixture to another pan without scraping scorched beans into new pot.
Add ham hocks and cook 45 minutes more.
Serve
Serve immediately.
On a heated serving platter, mound ¾ cup rice per serving at one end of platter, place ham hocks at other end, and put 1 cup beans per serving in middle.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dry red beans
- Break down during simmering to thicken the liquid into a creamy, starchy base.
- Ham hocks
- Release fat and collagen into the pot, adding savory depth and body to the broth.
- Celery, onions, and bell peppers
- Build the aromatic base of flavor that seasons the beans and cooking liquid.
- Cooked rice
- Serves as the neutral starch that the bean mixture is spooned over.
The step that matters
Simmering the beans after adding them back. Beans scorch easily on the bottom of the pan. Keeping them covered with liquid, stirring as needed, and moving the mixture to a new pot if scorching starts prevents a burnt taste.
