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 during the long gentle simmer.
Flour
Thickens the sauce and, cooked slowly, develops a good brown color.
Madeira wine
Adds depth and a rich, slightly sweet aroma to the sauce.
Butter
Adds richness and fat, carrying the herbs' flavor into the sauce.
Sugar
Adds a touch of sweetness that balances the wine and savory sauce.

The step that matters

Thicken the sauce with flour over a slow fire. Flour must be cooked slowly and stirred so it browns evenly and thickens without lumps or a raw starchy taste. High heat can scorch it, giving bitterness and uneven color.
