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
Ingredients
Directions
Prepare
Clean, scrape, and wash the turnips well.
Boil the turnips in water for 10 minutes, then drain.
Make the soup
Melt the butter in a stewpan over medium heat.
Sprinkle in the flour and stir.
Add the turnips, broth, salt and pepper; simmer until cooked.
For a sweeter version, use sugar instead of flour.
Finish
Optionally, mix in the beaten egg yolks just before serving.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour 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
- Turnips
- Provide the main bulk and body of the soup once simmered until tender.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Flour
- Thickens the soup by absorbing fat and liquid as it is stirred into the butter.
- Broth
- Supplies the cooking liquid and savoury flavour for the soup.
- Sugar
- Adds sweetness in the sweeter version, used in place of flour.
- Beaten egg yolks
- Enrich and thicken the soup slightly when stirred in at the end.
The step that matters
Mix in the beaten egg yolks just before serving. Egg yolks thicken through gentle heat and can curdle or scramble if the soup boils after they are added. Stir them in off the heat or over very low heat for a smooth, velvety result.
Swap the turnip
How well each one fits the dish's main ingredients (butter, flour, pepper, sugar, egg):
- Capsicumfits better
- Chivefits better
- Shallotfits better
- Turnipthe original
Fit is the average pairing score against butter, flour, pepper, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
