Why it works: Turnip and flour match in chemistry and in kitchens. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,874 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Turnips with Brown Sauce
Ingredients
Directions
Prepare the turnips
Peel the turnips, cut them into strips and dice.
Put the turnips in a saucepan, cover with boiling water, and simmer for about 30 minutes until half cooked.
Drain the turnips and place them in a skillet with 2 tablespoons of butter; fry until golden brown.
Make the brown sauce
Heat the clear soup and pour it over the turnips; simmer for 5 minutes.
While simmering, mix 1 teaspoon of flour with 2 teaspoons of butter and stir this mixture into the soup.
When the soup thickens to a custard-like consistency, pour it into a heated dish with a cover and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turnips
- Form the main body of the dish and, when browned in butter, add a caramelised, savoury flavour.
- Butter
- Browns the turnips in the skillet and enriches the sauce with fat and flavour.
- Flour
- Thickens the soup into a smooth, custard-like sauce when cooked with butter and liquid.
- Clear soup
- Forms the liquid base of the sauce, carrying flavour and becoming thick when simmered.
The step that matters
Thickening the sauce. Flour mixed with butter and stirred into hot soup must be blended smoothly and simmered so the starch swells and thickens evenly. Adding it unevenly or without enough heat can leave lumps or a thin, raw-tasting sauce.
Swap the turnip

Fit is the average pairing score against butter, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
