What each ingredient does

Lean meat from turtle
Forms the main body of the soup and gives it its meaty texture.
Callipee (turtle fat)
Adds richness and fat, carrying flavour through the soup.
Strong veal broth
Provides savoury depth and body to the soup base.
Flour
Thickens the liquid together with butter so the soup becomes body-rich.
Butter
Adds fat and richness, and combines with flour to thicken the soup.
12 onions, chopped
Adds sweetness and aromatic flavour as they cook down into the base.

The step that matters

Thickening the liquid with flour and butter. Flour must be cooked with butter and added gradually. Too much at once or too thick a mixture leaves lumps or a pasty texture, and the starch needs to be fully cooked to lose its raw taste.
