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

What each ingredient does

Sweet potatoes
Form the main body of the dish, becoming soft and tender as they bake.
Butter
Adds richness and moisture, helping the potatoes brown and carry the sweet glaze.
Sugar
Adds sweetness and caramelizes in the pan juices, forming a glossy glaze.

The step that matters

Basting often while baking. Spooning the pan sauce over the potatoes keeps their surfaces moist and lets the sugar and butter caramelize into a glaze rather than drying or burning.
