Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Vegetable marrow
Forms the body of the soup and gives it its main vegetable flavour and bulk.
Flour
Thickens the soup as its starch swells in the hot liquid.
Butter
Adds fat and richness, helping the marrow soften and carry flavour.
Milk
Adds creaminess and a soft, rounded body to the soup.

The step that matters

Stirring in the flour. Flour must be cooked into the melted butter and marrow and stirred until the mixture thickens. Adding liquid too early can leave lumps, because starch granules clump before they can disperse evenly in the liquid.
