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 ↓
Cup Custards
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.
Make the custard base
Boil the lemon peel in the milk.
Strain the milk and let it cool.
Beat the eggs well and add them to the cooled milk.
Stir in sugar to taste, and add nutmeg and wine if desired.
Mix well and pour the mixture into cups.
Bake and serve
Bake in a 350°F (175°C) oven until thick, then remove immediately to avoid whey.

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
- Coagulate on heating to set the custard into a thick, sliceable texture.
- Milk
- Forms the liquid body of the custard, carrying the eggs and flavour.
- Sugar
- Adds sweetness and balances the flavour of the milk and eggs.
The step that matters
Remove the custards from the oven immediately once thick. Egg proteins keep setting from residual heat, and overbaking causes the custard to curdle and weep whey.
Swap the nutmeg
The recipe marks nutmeg as optional. How well each one fits the dish's main ingredients (milk, lemon, egg, sugar, wine):
- Cinnamonfits better
- Nutmegthe original
- Tarragonfits about as well
- Thymefits less well
Fit is the average pairing score against milk, lemon, egg, sugar, wine. Candidates are from the same food group and used in at least 100 recipes.
