Why it works: Pumpkin and butter are a kitchen classic. They rank in the top 20% of all ingredient pairs, and cooks put them together in 1,933 recipes. Both carry 2,3-pentanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pumpkin
- Forms the puree itself; boiling softens it so it can be mashed smooth.
- Butter
- Adds fat and richness, giving the puree a smoother mouthfeel and flavour.
The step that matters
Squeeze the pumpkin until very dry. Pumpkin holds a lot of water. Excess moisture left in the puree makes it thin and watery, so squeezing it dry before mashing gives a thicker, more concentrated result.
Swap the pumpkin
How well each one fits the dish's main ingredients (pepper, butter):
- Lemonfits better

Fit is the average pairing score against pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
