Why it works: Turnip and onion match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 7,585 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Turnip Souffle
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the base
Make a white sauce by melting the butter, adding the flour, and enough milk to create a thick consistency.
In a bowl, combine the white sauce, strained cooked turnip, chopped onion, salt, and cayenne.
Assemble and bake
Gently fold in the beaten egg whites last.
Pour the mixture into a well-buttered pan.
Bake in a slow oven at 300°F (150°C) until a delicate brown.

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
- Egg whites
- Beaten whites trap air, giving the soufflé its light, risen structure as it sets.
- Turnip
- Provides the main body and flavour, adding moisture to the thick base.
- Flour
- Thickens the butter and milk into a white sauce that holds the mixture together.
- Butter
- Enriches the white sauce and adds richness and flavour to the base.
- Milk
- Combines with the flour and butter to form the thick white sauce that gives body.
The step that matters
Gently fold in the beaten egg whites last. Beaten egg whites hold trapped air that makes a soufflé rise. Stirring vigorously knocks this air out, so the soufflé bakes flat and dense. Folding gently keeps the foam intact.
Swap the turnip
How well each one fits the dish's main ingredients (butter, flour, milk, sauce, egg, onion):
- Chivefits better
- Potatofits better
- Shallotfits better
- Turnipthe original
Fit is the average pairing score against butter, flour, milk, sauce, egg, onion. Candidates are from the same food group and used in at least 100 recipes.
