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 and bulk of the soup, softening during simmering.
- Clarified butter
- Fat for frying that promotes browning of the turnips' surface.
- White sugar
- Adds sweetness and helps the turnips caramelise to a cinnamon-brown colour.
- Brown consommé
- Forms the liquid base of the soup and carries its savoury flavour.
The step that matters
Frying the turnips until cinnamon brown. Sugar caramelises and butter browns at high surface heat, so the turnips can scorch before they colour evenly. Drying them well first keeps them from steaming, which helps them brown.
Swap the turnip
How well each one fits the dish's main ingredients (butter, sugar):
- Sweet potatofits better
- Leekfits better
- Potatofits better
- Turnipthe original
Fit is the average pairing score against butter, sugar. Candidates are from the same food group and used in at least 100 recipes.
