Why it works: Turnip and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 2,842 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
A Good Beef Soup
Ingredients
Directions
Make the broth
Combine soup bone and cold water in a large pot.
Add salt.
Bring to a boil.
Reduce heat and simmer for 2 hours.
Add vegetables

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 water during the long simmer, giving the broth body.
- Potatoes
- Soften during cooking and add starch that gives the soup more body.
- Eggs
- Whisked and stirred into the hot strained soup, they thicken it lightly and add richness.
The step that matters
Gradually straining soup into the eggs. Adding hot soup slowly while stirring gently warms the eggs evenly. Pouring too fast or without stirring can scramble the eggs and cause curdling.
Swap the onion
How well each one fits the dish's main ingredients (potato, turnip, parsley, egg):
- Leekfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against potato, turnip, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
