Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White sugar
- Adds sweetness and helps structure the filling as it is creamed with butter.
- Butter
- Adds fat and richness, and creaming it with sugar traps air for a smoother texture.
- Eggs
- Set during baking to thicken the filling and give it structure.
The step that matters
Bake until set. Eggs thicken as their proteins coagulate with heat. Underbaking leaves the filling runny, while overbaking can make it curdle or weep, so watch for the filling to firm up without bubbling hard.
