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

What each ingredient does

Sweet potatoes: Provide the bulk and soft, creamy body of the filling.
Eggs: Set the filling and bind the custard-like texture as it bakes.
Unsalted butter: Adds richness and fat that carries flavor and helps the topping turn tender.
Light brown sugar: Adds sweetness and caramel notes, and helps the topping brown.
Pecan halves: Add crunch and toasty flavor to the topping as it bakes.

The step that matters

Bake pie until set, about 45 minutes. Eggs set as they heat, so underbaking leaves the filling loose and watery, while overbaking can make it dry and cracked. Check that the center has firmed before removing it.

Swap the sweet potato

How well each one fits the dish's main ingredients (sugar, honey, egg, vanilla, cinnamon, nutmeg, clove):

Arrowrootfits about as well
Capsicumfits less well
Parsnipfits less well

Fit is the average pairing score against sugar, honey, egg, vanilla, cinnamon, nutmeg, clove. Candidates are from the same food group and used in at least 100 recipes.
