Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Gumbo Soup
Ingredients
Directions
Make the stock
Combine veal, fowl, carrots, turnips, onion, and water in a soup pot. Boil for 5 hours.
Remove the fowl, cut into small pieces, and set aside.
Make the roux and finish the soup
Fry sliced onions in butter in a pan until brown, then remove the onions.
Add the fowl pieces to the pan and fry until brown.
Add a little flour to the hot butter in the pan, stirring constantly to avoid burning.
Combine the fried onions and fowl with the soup, strain into the mixture, and boil for 30 minutes.
Wash oysters, strain their liquor into the soup, add oysters, and bring to a boil.
Mix gumbo with cold water, stir into the soup while boiling, but do not let it boil after adding gumbo.
Serve
Serve the soup with boiled rice, adding a spoonful to each plate.

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 in the hot butter, giving the gumbo body.
- Butter
- Carries the browning of the onions and fowl and adds richness to the base.
- Oysters
- Add briny flavour and a soft, tender texture to the finished soup.
- Fowl
- Frying until brown deepens the savoury flavour of the broth.
The step that matters
Stirring in the gumbo. Once the gumbo is added, the soup must not boil again, because prolonged high heat can break down its thickening and make the texture stringy or grainy.
Swap the onion
How well each one fits the dish's main ingredients (veal, carrot, turnip, butter, flour, oyster, rice):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against veal, carrot, turnip, butter, flour, oyster, rice. Candidates are from the same food group and used in at least 100 recipes.
