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.

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 as they stew, thickening the soup and giving it body.
- Veal knuckle
- Releases gelatin and flavour into the water, giving the stock richness and body.
- Onions
- Soften and sweeten as they stew, building the savoury base of the soup.
- Asparagus tops
- Add tender texture and fresh green flavour when cooked briefly at the end.
- Cabbage hearts
- Add body and mild sweetness while staying tender in the hot soup.
The step that matters
Keeping the vegetables bright green. Green vegetables turn dull olive when overcooked, because acids released in cooking change the chlorophyll. Stewing them only until tender, and adding them late, keeps their colour bright.
