Why it works: Turnip and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,418 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Potage Aux Navets, or Turnip Soup
Ingredients
Directions
Prepare
Cut the turnips into 1‑inch squares and shape them like barrels.
Soak the turnips in water while preparing.
Clarify the butter in a shallow stewpan over medium heat.
Drain the turnips and fry them in the clarified butter until golden brown.
Transfer the fried turnips to a sieve to drain excess butter.
Make the soup
Combine the turnips with sugar, salt, and consommé in a soup pot.
Place the pot by the stove and let it boil gently, skimming and clarifying as needed.
Add blanched celery heads at the beginning for extra flavor.
Serve
Serve with bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Provide the main body of the soup, and browning in butter adds color and a sweeter, nutty flavor.
- Butter
- Frying in clarified butter browns the turnips and adds richness to the dish.
- Sugar
- Adds sweetness that balances the mild bitterness of turnips.
- Consommé
- Supplies the liquid base and savory flavor of the soup.
The step that matters
Frying the turnips until golden brown. Turnips fried in clarified butter brown through the Maillard reaction, which builds flavor. Clarified butter has no milk solids to burn, so it can reach browning heat without scorching. Drain them well so excess butter does not carry into the soup.
Swap the celery
How well each one fits the dish's main ingredients (turnip, butter, sugar):
- Cinnamonfits better
- Capersfits better
- Nutmegfits better
- Celerythe original
Fit is the average pairing score against turnip, butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
