Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 to the base before the flour is cooked in.
- Flour
- Thickens the soup as it cooks with the butter and liquid.
- Pearl barley
- Provides the main body and chewy texture of the soup as it simmers.
- Milk
- Adds creaminess and a softer, richer flavour to the soup.
- Chicken or veal stock
- Supplies savoury meat flavour and most of the liquid in the soup.
- Corn starch
- Adds extra thickening so the soup becomes smoothly body-rich when boiled.
The step that matters
Adding the boiling water and milk. Adding liquid slowly while stirring keeps the flour and starch from clumping into lumps, so the base blends smoothly before it simmers.
