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

What each ingredient does

Eggs: Set the filling into a custard-like structure as they cook.
Butter: Adds richness and fat, giving the filling a tender, smooth texture.
All-purpose flour: Thickens the filling and helps it hold its shape when baked.
Light brown sugar: Adds sweetness and moisture, along with caramel-like flavor.
Pecan pieces: Add toasty flavor and crunchy texture against the soft filling.
Semi-sweet chocolate chips: Melt into the filling, adding chocolate flavor and pockets of richness.

The step that matters

Bake until just set. Eggs keep setting as the pie cools, so overbaking can make the filling dry, cracked or rubbery. Pull it out when the centre is just set and the top is golden brown.
