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

What each ingredient does

Sweet potatoes: Form the bulk of the casserole and turn tender and soft during baking.
Apple: Adds moisture and a fruity sweetness that balances the sweet potatoes.
Brown sugar or syrup: Adds sweetness and helps the top caramelize and brown in the oven.
Butter or substitute: Adds fat and richness, carrying flavour across the top of the dish.

The step that matters

Cover and bake until tender. Covering traps steam so the sweet potatoes and apple cook through evenly and soften. Removing the cover only afterwards lets the surface dry and brown, so uncovering too early can leave the slices firm inside.
