Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Vegetable Soup
Ingredients
Directions
Make the broth
Scrape the outside of the soup bone clean and cut the lean meat into 1-inch cubes.
Place the bone and meat in a soup kettle with 2 quarts of cold water.
Let it stand for 30 minutes on the back of the stove.
Gradually heat to boiling, removing scum as it arises.
Cover and cook slowly for 4 to 5 hours, keeping below boiling point.
Remove from heat, drain the bone and meat, and let cool.
Once cool, remove the fat from the top.
Add the vegetables
Return the broth to the stove and add cabbage, potato, onion, tomatoes, celery leaves, barley, sago, and salt to taste.
Boil for 1 hour.
Make the noodles and serve
For the noodles, beat 1 unbeaten egg with flour, adding salt and baking powder.
Add enough flour to make a stiff batter.
Drop spoonfuls of the batter into the boiling soup and cook until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup bone
- Releases flavor and gelatin into the broth during the long, slow simmer.
- Lean meat
- Adds savory meat flavor to the broth and becomes tender during slow cooking.
- Potato
- Thickens the broth slightly as it cooks and adds starchy body.
- Egg
- Binds the noodle batter so the dumplings hold their shape in the soup.
- Tomatoes
- Adds acidity and brightness to the broth.
- Cabbage
- Adds bulk and mild sweetness as it softens in the broth.
The step that matters
Keeping the broth below a boil during the 4 to 5 hour simmer. Gentle heat lets collagen and flavor leach out slowly while keeping the broth clear. A hard boil makes it cloudy and can toughen the meat.
Swap the cabbage
How well each one fits the dish's main ingredients (meat, potato, onion, tomato, celery, barley, egg):
- Leekfits better
- Carrotfits better
- Asparagusfits better
- Cabbagethe original
Fit is the average pairing score against meat, potato, onion, tomato, celery, barley, egg. Candidates are from the same food group and used in at least 100 recipes.
