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 body of the filling, giving it a soft, smooth texture.
Eggs
Bind the filling and help it set into a firm custard as it bakes.
Butter
Adds richness and fat, contributing tenderness and a smooth mouthfeel.
Sugar
Adds sweetness and helps brown the surface of the pie as it bakes.
Lemon juice
Adds acidity that brightens the flavour and balances the sweetness.

The step that matters

Beat the eggs until very light. Beating incorporates air into the eggs, which helps the filling become light and smooth. Well-combined eggs blend evenly into the mashed potato, avoiding streaks and uneven setting in the baked pie.

Swap the sweet potato
