Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the soup and carries flavour as the base of the roux.
- Flour
- Thickens the stock into a smooth, lightly bodied soup as it cooks with the butter.
- Stock
- Forms the main liquid and gives the soup its savoury flavour.
- Cream
- Adds richness and a smooth, velvety texture.
The step that matters
Adding the stock to the roux. Pouring the stock in gradually while stirring constantly keeps the flour dispersed, so the soup thickens smoothly instead of forming lumps.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
