Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrows
- Provide the main body and bulk of the puree once cooked and sieved.
- Butter
- Adds fat and richness, carrying the flavour of the softened onion.
- Onion
- Sweetens and builds savoury aroma as it fries gently in butter.
- White stock or milk
- Supplies liquid to simmer the marrow until tender and thin the puree.
- Heavy cream
- Adds fat and a smooth, velvety texture to the finished puree.
The step that matters
Pass the vegetables through a fine sieve. Sieving breaks down fibres and removes any remaining stringy or seedy bits, which is what gives the puree a smooth texture. Drain well first so excess liquid does not make the puree thin.
Swap the onion
How well each one fits the dish's main ingredients (butter, milk, sugar, cream):
- Potatofits better
- Sweet potatofits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against butter, milk, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
