Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Puree of Vegetable Marrow
Ingredients
Directions
Prepare
Pare, quarter, and remove the pith and seeds from the vegetable marrows.
Make the puree
In a stewpan, melt the butter and fry the sliced onion for 5 minutes.
Add the marrows, white stock or milk, salt, and sugar; simmer until the vegetables are tender.
Drain the mixture and rub it through a fine sieve.
Incorporate the puree with the stock or milk it was simmered in.
Finish and serve
Stir in the cream, adjust seasoning to taste, and serve with fried croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vegetable marrows
- Form the bulk of the puree, providing the main body and mild flavor.
- Butter
- Adds richness and carries the flavor of the frying onion.
- Onion
- Adds savory aroma and depth as it softens in butter.
- White stock or milk
- Cooks the marrows and adds moisture to loosen the puree.
- Cream
- Adds fat and a smooth, silky texture to the finished puree.
The step that matters
Rubbing the puree through a fine sieve. Pressing the cooked vegetables through a fine sieve breaks down fibers and removes any remaining pieces of skin or seeds, which gives a smooth texture. Skipping or rushing this step leaves the puree grainy and stringy.
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.
