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

What each ingredient does

Turtle
Provides the main meat, which becomes tender through long simmering in the soup.
Soup stock
Forms the liquid base that carries the flavour of the whole soup.
Butter
Adds richness and a browned, nutty aroma at the start of the base.
Flour
Thickens the soup as it cooks, giving it body.
Ham
Adds savoury, salty depth to the base.
Canned tomatoes
Adds acidity and body, rounding out the soup's flavour.

The step that matters

Stir in the flour until smooth. Flour lumps form if it meets hot liquid unevenly. Stirring it into the fat and aromatics until smooth lets starch disperse so the soup thickens evenly.

Swap the nutmeg
