Why it works: Turnip and leek match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,046 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Spring Soup
Ingredients
Directions
Make the base
Combine veal, ham, peas, turnips, leek, and celery in a large pot with 4 quarts of soft water.
Boil until the meat releases its juices and the peas are soft.
Remove the meat and vegetables, then strain the peas through a sieve.
Finish the soup
Season the soup with pepper and coarse sea salt to taste.
Add chopped asparagus, cabbage lettuce hearts, and mint to the soup and simmer until tender.
If the soup is too thick, add broth; if too thin, mix in flour and water.
For a greener color, add strained spinach juice but do not boil.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Whole white peas
- Break down while boiling to thicken the soup and give it body.
- Veal knuckle
- Releases juices and gelatin during boiling to add savory depth to the broth.
- Asparagus
- Adds tender texture and fresh vegetable flavor to the finished soup.
- Cabbage lettuce hearts
- Soften during simmering, adding mild vegetable flavor and tender body.
- Turnips
- Soften during boiling, adding mild sweetness and earthy flavor to the base.
The step that matters
Adding spinach juice without boiling. Chlorophyll turns olive-brown when heated, so boiling dulls the green color. Adding strained spinach juice off the boil keeps the color bright.
