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 give it a soft, creamy body.
Eggs: Bind the mashed sweet potato so the base sets into a spoonable custard.
Butter: Adds richness and fat, carrying flavor and keeping the texture tender.
Granulated sugar: Adds sweetness and helps the base taste balanced against the potatoes.
All-purpose flour: Thickens the topping mixture so it becomes crumbly rather than runny.
Pecans: Provide a toasty, crunchy contrast to the soft base.

The step that matters

Cover and cook on high for 3 to 4 hours. Slow cookers vary in heat, and the eggs can curdle or the base can stay loose if overcooked or undercooked. Check that the centre is set and the topping is cooked through before serving.

Swap the sweet potato
