Why it works: Beans and onion match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 5,242 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Recipe for Black Bean Soup
Ingredients
Directions
Make the soup
Combine one pint of black beans or turtle beans, 1 small onion, 4 quarts of water, 1 small chicken, or ½ large one, or else 1 lb. beef and a slice of middling bacon.
When the soup is nearly done, chop up the meat which has been boiled in it.
Make the meat balls
Season it with pepper and salt and make it into balls.
Roll them in egg white and dry them on the stove.
Finish and serve
When the soup is ready to be served, strain off the beans, add a wineglass of walnut or tomato catsup and a wineglass of good sherry, then add the chopped hard‑boiled eggs and the meat balls to the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Black beans
- Form the body of the soup and give it its earthy flavor and thickness.
- Egg white
- Binds the meat balls' surface so they hold together and dry to a firm coat.
- Hard-boiled eggs
- Add a firm, mild texture and body to the finished soup.
- Sherry
- Adds aromatic depth and a touch of acidity to the finished soup.
The step that matters
Drying the meat balls on the stove. Rolled meat balls need their egg white coat to dry and set before they go into the soup; wet coating can slide off or cook unevenly, so drying gives a firm, intact exterior.
Swap the walnut
