Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down when boiled to give the soup body and a smooth, thick texture after straining.
- Leeks or onions
- Build savoury flavour as they soften in the butter and water base.
- Flour
- Thickens the milk and strained vegetable liquid so the soup becomes creamy and lightly body-rich.
- Milk
- Adds richness and creaminess, softening the soup's flavour and texture.
- Butter
- Adds fat for a rounder, richer mouthfeel and carries flavour.
The step that matters
Adding the flour-milk mixture. Flour clumps if added dry or unmixed. Whisking it into cold milk first and then stirring while it heats keeps the starch dispersed, so the soup thickens smoothly instead of lumping.
