Why it works: Nutmeg and mace are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 6,557 recipes. Both carry myristicin, which smells spice, warm. The science ↓

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):
- Cinnamonfits better
- Parsleyfits better
- Cardamomfits better
- 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.
