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 ↓

A PLAIn Custard

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Beat the eggs until light.

  2. Add sugar and salt, then mix in the milk, nutmeg, and lemon peel.

Bake

  1. Pour the mixture into an earthen dish.

  2. Place the dish in a larger tin filled with water.

  3. Bake in a slow oven at 300°F (150°C) until set, checking with a spoon.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Coagulate when heated, setting the custard into a firm, sliceable body.
Milk
Provides the liquid base and moisture that gently cooks into a smooth custard.
Sugar
Adds sweetness and balances the savory-leaning richness of the eggs and milk.

The step that matters

Baking in a water bath until just set. Egg proteins set at moderate heat; overbaking or direct high heat causes curdling and a grainy, weeping texture. The surrounding water keeps the dish gentle, and checking with a spoon helps catch the point where the custard is firm but still creamy.

Swap the nutmeg

How well each one fits the dish's main ingredients (egg, sugar, milk, lemon):

  1. Cinnamonfits better
  2. Nutmegthe original
  3. Dillfits less well
  4. 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.
