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

What each ingredient does

Butter
Adds richness and body, and helps carry the spice flavour.
Flour
Rubbed in with butter to thicken the soup and give it body.
Eggs
Beaten eggs stirred in to add richness and help bind the soup.
Port wine
Adds sweetness, depth and acidity to the soup.

The step that matters

Stirring in the flour and butter. Flour added directly to hot liquid clumps; rubbing it into butter first coats the starch granules so they disperse and thicken smoothly.
