Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Turnip Soup
Ingredients
Directions
Make the broth
Remove all the meat from the knuckle of veal for cutlets and set the remainder 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 until the next day.
Skim off the fat and sediment.
Finish the soup
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.
Let a small roll simmer in the soup until soaked through.
Serve the soup thickened to the consistency of medium cream.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the soup as it cooks, giving it a smooth, creamy body.
- Cream
- Adds richness and a smooth, velvety texture to the soup.
- Butter
- Adds fat, richness and flavour, and helps the flour blend smoothly.
- Small roll
- Soaks up liquid and gives the soup body as it breaks down.
- Veal knuckle
- Contributes gelatin and savoury meaty flavour to the broth as it stews.
The step that matters
Skim off the fat and sediment. Fat and sediment left in the chilled broth would spoil the flavour and clarity of the soup, so they must be removed before reheating.
Swap the mace
How well each one fits the dish's main ingredients (veal, onion, pepper, flour, cream, walnut, butter):
- Nutmegfits better
- Parsleyfits better
- Sagefits better
- Macethe original
Fit is the average pairing score against veal, onion, pepper, flour, cream, walnut, butter. Candidates are from the same food group and used in at least 100 recipes.
