Why it works: Walnut and nutmeg match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,230 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Irish Potato Pie
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare the filling
Preheat the oven to 350°F (175°C).
In a bowl, combine the beaten eggs and sugar.
Add the beaten potatoes, rich cream, and butter; mix well.
Flavor the mixture with nutmeg and brandy.
Bake and serve
Pour the filling into two pie crusts.
Bake for 30-40 minutes or until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard-like filling as they cook, giving it structure.
- Sugar
- Adds sweetness and helps the filling brown lightly as it bakes.
- Potatoes
- Provide body and a dense, smooth texture to the filling.
- Rich cream
- Adds fat and moisture, making the filling soft and rich.
- Butter
- Adds fat and richness, contributing flavor and a tender texture.
The step that matters
Bake until set. Eggs firm up as they heat, so the filling needs enough time in the oven to set. Pulling it too early leaves a runny center, while overbaking can make it dry or cracked.
Swap the potato
How well each one fits the dish's main ingredients (egg, sugar, cream, walnut, butter, nutmeg, brandy):
- Sweet potatofits better
- Shallotfits better
- Spinachfits about as well
- Potatothe original
Fit is the average pairing score against egg, sugar, cream, walnut, butter, nutmeg, brandy. Candidates are from the same food group and used in at least 100 recipes.
