Why it works: Nutmeg and lemon 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 ↓
Custard Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
In a saucepan, boil the milk.
In a bowl, beat the eggs, sugar, nutmeg, lemon zest, and salt together.
Make the custard
Slowly add the hot milk to the egg mixture, stirring constantly.
Pour the mixture into a pie crust.
Bake
Bake in the preheated oven until set, about 30-40 minutes.

Egg and nutmeg barely smell alike, yet cooks put them together in 24,744 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard as they cook, giving it structure and a firm texture.
- Milk
- Provides the liquid base that sets with the eggs into a smooth custard.
- Sugar
- Sweetens the custard and softens its set slightly.
- Lemon zest
- Adds bright aromatic oils that lift the flavour of the custard.
The step that matters
Adding the hot milk to the eggs. Pouring hot milk into eggs too quickly, or without constant stirring, can scramble the eggs. Adding it slowly while stirring gently warms the eggs so the custard stays smooth.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk, lemon):
- Cinnamonfits better
- Nutmegthe original
- Dillfits less well
- Gingerfits less well
Fit is the average pairing score against egg, sugar, milk, lemon. Candidates are from the same food group and used in at least 100 recipes.
