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

What each ingredient does

Sweet potatoes: Provide the main body and natural sweetness that browns in the pan.
Butter or dripping: Conducts heat for frying and adds richness and browning to the surface.

The step that matters

Fry the sweet potatoes until browned. Frying over medium‑high heat in fat browns the starches and sugars on the surface through the Maillard reaction, giving flavor and color. Too little heat or crowded pieces steam the potatoes instead, leaving them pale and soft.
