Why it works: Parsley and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 9,057 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Spring Soup
Ingredients
Directions
Make the base
In a large pot, combine water, veal, ham or bacon, green split peas, onions, turnips, parsley, thyme, celery, and leek.
Stew the mixture until the peas are very soft.
Remove the meat and press the remaining mixture through a fine sieve.
Season the soup with pepper and coarse sea salt.
Add vegetables and colour
Chop the asparagus tops, cabbage hearts, and mint, then stew them until tender, keeping them bright green.
Add the vegetables to the soup 15 minutes before serving.
If the soup isn't green enough, pound some spinach, squeeze the juice through a cloth, and add ¼ pint to the tureen before pouring in the soup.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green split peas
- Break down when stewed to thicken the soup and give it body.
- Veal knuckle
- Releases gelatin and flavour into the broth, giving it richness and body.
- Onions
- Soften and sweeten as they stew, adding savoury depth to the base.
- Asparagus tops
- Add tender texture and fresh green flavour when stewed briefly.
- Cabbage hearts
- Add soft texture and mild sweetness as they stew until tender.
- Spinach juice
- Adds green colour to the finished soup.
The step that matters
Keeping the vegetables bright green. Green vegetables turn olive-brown when overcooked because acids released during cooking break down chlorophyll. Stewing them only until tender and adding them late helps preserve their colour.
