Why it works: Butter and sugar are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 98,233 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓
Potage Aux Navets, or Turnip Soup
Ingredients
Directions
Prepare
Soak the cut turnips in water until ready.
Clarify the butter in a shallow saucepan over medium heat.
Fry and drain
Drain the turnips and fry them in the clarified butter until golden brown.
Transfer the fried turnips to a sieve to drain excess butter.
Simmer in consommé
Place the turnips in a soup pot, add a little sugar and salt, and fill with consommé.
Bring to a gentle boil, skimming the surface as needed.
For added flavor, include blanched celery heads at the beginning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the body of the soup and, once fried, develop a golden, browned surface.
- Butter
- Fries the turnips to a golden brown and adds richness.
- Consommé
- Forms the liquid base that carries the flavor of the soup.
The step that matters
Fry the turnips until golden brown. Frying in clarified butter browns the surface through the Maillard reaction, which adds deep savory flavor. Clarified butter has no milk solids to burn, so it can reach browning temperatures without scorching. Drain well so excess fat does not dilute the broth.
Swap the turnip
How well each one fits the dish's main ingredients (butter, sugar):
- Sweet potatofits better
- Leekfits better
- Potatofits better
- Turnipthe original
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
