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

What each ingredient does

Cold boiled sweet potatoes: Form the main body of the dish, holding their shape while the outside browns in fat.
Flour: Dusted on the slices to help form a light, golden crust when sautéed.
Butter or sweet dripping: Conducts heat and carries flavor, and helps the surface brown in the pan.

The step that matters

Sauté until lightly colored. Cooking over steady heat in enough fat lets the flour and starch on the surface brown without the slices burning or going soft inside. Too little fat or too high heat can scorch the coating before the slices heat through.
