Why it works: Sugar and molasses are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 9,225 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓

Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Beat the egg in a bowl.
Stir in the sugar, molasses, and salt.
Add the milk and nutmeg, mixing well.
Pour the mixture into custard cups.
Bake
Place the cups in a baking pan filled with water.
Bake at 300°F (150°C) until creamy, without boiling.

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
- Egg
- Sets the custard into a creamy, tender structure as it heats.
- Milk
- Provides the liquid base and moisture that gives the custard its smooth body.
- Sugar
- Adds sweetness and softens the flavor of the custard.
- Molasses
- Adds depth of flavor and a darker color along with sweetness.
The step that matters
Bake at 300°F (150°C) until creamy, without boiling.. Eggs set through gentle heat; if the custard gets too hot or boils, the proteins tighten too far and the texture turns grainy or watery. A water bath moderates the heat, so the cups cook evenly.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, milk, molasses):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits about as well
- Allspicefits less well
Fit is the average pairing score against egg, sugar, milk, molasses. Candidates are from the same food group and used in at least 100 recipes.
