Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, carrying flavour through the vegetables as they cook.
- Carrots
- Provide sweetness and body, thickening the puree once cooked and sieved.
- Onions
- Add savoury depth and aroma as they soften in butter.
- Leeks
- Contribute a mild onion-like flavour and soft body to the puree.
- Turnips
- Add earthy flavour and bulk, helping give the puree its body.
The step that matters
Skimming while bringing the water to a boil. Foam and impurities rise to the surface as the liquid heats. Removing them keeps the puree clean-tasting and smooth rather than gritty or scummy.
