Why it works: Cabbage and pepper are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 4,081 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Rivel Soup
Ingredients
Directions
Make the broth
Boil the beef, cabbage, onion, tomatoes, and carrot in a large pot for three hours.
Strain the broth and return it to the pot.
Make the rivels and finish
Mix the flour and egg in a bowl until combined.
Cut the mixture with a knife until it forms small pieces (rivels).
Add the rivels to the broth and boil for five minutes.
Season with salt and pepper to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the flour into a stiff dough that can be cut into small rivels.
- Flour
- Forms the starch-based dough pieces that hold their shape and thicken the broth slightly.
- Beef
- Releases flavor and savory body into the broth during long simmering.
- Onion
- Adds aromatic sweetness and depth to the broth as it cooks.
- Tomatoes
- Contribute acidity and savory depth to the broth.
The step that matters
Cut the mixture into small pieces. The dough must be cut into evenly small, dry-surfaced rivels; pieces that are too large cook unevenly, and overworked dough becomes tough and chewy rather than tender.
Swap the cabbage
How well each one fits the dish's main ingredients (beef, onion, tomato, carrot, egg, flour, pepper):
- Capsicumfits better
- Potatofits better
- Okrafits better
- Cabbagethe original
Fit is the average pairing score against beef, onion, tomato, carrot, egg, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
