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

What each ingredient does

Potatoes
Provide the starchy bulk that gives the pie its body once mashed fine.
Butter
Adds richness and a tender, smooth texture when creamed with sugar.
Eggs
Beaten and folded in to lighten the filling and help it set with structure.
Sugar
Sweetens the filling and helps the butter cream to a light, fluffy base.

The step that matters

Adding the mashed potatoes while warm, not hot. Potatoes that are too hot can cause the butter to melt and separate, while cold potatoes stiffen the creamed mixture and make it lumpy. Warm potatoes blend smoothly and keep the batter airy when the eggs are folded in.

Swap the potato

How well each one fits the dish's main ingredients (butter, egg, sugar, lemon, nutmeg):

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