Why it works: Onion and turnip match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 7,585 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Turnip Soup
Ingredients
Directions
Make the broth
Remove all the meat from the knuckle of veal for cutlets.
Set the remainder of the knuckle to stew with the onion, herbs, mace, and water.
Cover and simmer on low heat for 4 to 5 hours.
Strain the broth and refrigerate overnight.
Remove the fat and sediment from the broth.
Finish and serve
Simmer the broth with diced turnips until tender, seasoning with salt and pepper.
Mix the flour with the cream and butter until smooth.
Add the mixture to the soup and let a small roll simmer in the soup until soaked through.
Serve the soup thickened to the consistency of medium cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle
- Releases gelatin and flavour into the broth as it stews, giving body and savour.
- Turnips
- Provide the main vegetable flavour and soften to give the soup its body.
- Cream
- Adds richness and smoothness, softening the soup's flavour and texture.
- Flour
- Thickens the soup by starch absorbing liquid when heated with fat and cream.
- Butter
- Adds fat for richness and helps the flour blend smoothly into the cream.
- Small roll
- Soaks up broth, adding bread body and thickening the soup further.
The step that matters
Mixing the flour with cream and butter until smooth. Flour added directly to hot liquid forms lumps because its starch clumps before it can disperse. Blending it first with fat and cold cream lets the starch separate evenly, so the soup thickens smoothly.
Swap the mace
How well each one fits the dish's main ingredients (veal, onion, turnip, pepper, flour, cream, walnut):
- Celeryfits better
- Capersfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against veal, onion, turnip, pepper, flour, cream, walnut. Candidates are from the same food group and used in at least 100 recipes.
