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

What each ingredient does

Mashed potato
Provides the bulk and body of the filling, giving a soft, custard-like texture.
Butter
Adds richness and fat, creating a tender, smooth texture when creamed with sugar.
White sugar
Sweetens the filling and helps the creamed butter hold air for a lighter texture.
Eggs
Egg yolks enrich and set the filling, while whipped whites add lift and lightness.
Lemon juice
Adds acidity that brightens the sweet filling and balances its richness.

The step that matters

Folding in the whipped egg whites. Stiff whites hold air that gives lightness; overmixing deflates them, leaving a dense pie. Fold gently, just until no white streaks remain.

Swap the mace

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

  1. Cinnamonfits better
  2. Parsleyfits better
  3. Cardamomfits better
  4. Macethe original

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