Why it works: Lemon and nutmeg match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 11,318 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Potato Pie
Ingredients
Directions
Prepare the filling
Boil the potatoes until tender, then mash them very fine.
In a separate bowl, cream the butter and sugar together until light and fluffy.
Add the mashed potatoes to the butter mixture while still warm, but not hot.
Finish and serve
Beat the egg whites and yolks separately.
Fold the beaten eggs into the potato mixture.
Flavor with lemon juice and sprinkle a little grated nutmeg on top before serving.

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):
- Shallotfits better
- Sweet potatofits better
- Arrowrootfits better
- Potatothe original
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.
