Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Old-fashioned Vegetable Soup
Ingredients
Directions
Make the broth
Place the beef, veal, and mutton in a large soup kettle and cover with water. Do not add salt.
Bring to a simmer and let it cook all day.
In the evening, remove from heat and cool overnight.
Finish the soup
In the morning, add the carrots, potatoes, onion, turnip, cabbage, soup greens, tomatoes, barley, salt, pepper, and brown sugar.
Cook for 2 to 3 hours until the vegetables are tender.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef shin
- Long simmering breaks down collagen, giving the broth body and rich flavor.
- Veal knuckle
- Bones and connective tissue release gelatin, adding body and a silky mouthfeel to the broth.
- Mutton
- Adds deep meaty flavor to the broth during the long simmer.
- Barley
- Absorbs liquid as it cooks, thickening the soup and adding chewy texture.
- Potatoes
- Starch softens during cooking, helping thicken the broth and giving body to the soup.
- Tomatoes
- Add acidity and sweetness that balance the rich meats and vegetables.
The step that matters
Cooling overnight before adding vegetables. Chilling lets fat solidify on the surface so it can be removed, and the broth's gelatin sets, producing a cleaner, less greasy soup once reheated.
Swap the turnip

Fit is the average pairing score against beef, veal, mutton, meat, carrot, potato, onion. Candidates are from the same food group and used in at least 100 recipes.
