Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brussels sprouts
- Form the main body of the puree, contributing bulk, flavor, and a smooth texture once sieved.
- Butter
- Adds fat and richness, carrying flavor during the initial gentle sweating.
- Flour
- Thickens the puree as it heats, giving it body.
- Milk
- Adds moisture and creaminess, softening the puree's finish.
- Stock
- Provides the liquid base and savory depth as the vegetables simmer.
The step that matters
Rub the mixture through a fine sieve. Sieving breaks down the cooked fibres and separates out skins and stringy pieces, which is what makes the puree smooth rather than grainy. Pressing the solids through in batches gives the finest result.
