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

What each ingredient does

Flour
Thickens the butter and stock mixture into a smooth, body-rich soup.
Butter
Carries the frying of the vegetables and forms the base for the flour thickener.
Oxtail
Contributes meaty flavour and richness to the broth during the long simmer.
Onions
Soften and sweeten while frying, adding savoury depth to the soup.
Carrots
Add natural sweetness and body to the vegetable base.

The step that matters

Cooking the flour in the butter. Cooking the flour in melted butter for a few minutes removes its raw taste and lets it thicken smoothly when the liquid is added, so the soup does not turn lumpy or pasty.

Swap the onion
