Why it works: Molasses and sugar 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 ↓
Molasses 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.
Make the custard
Melt the molasses and butter together on low heat until well mixed, then let cool.
In a separate bowl, beat the eggs and add the sugar, mixing until combined.
Stir the cooled molasses mixture into the egg and sugar mixture. Add nutmeg or cinnamon to taste.
Bake
Fill pie crusts generously with the mixture and bake in a slow oven at 300°F (150°C) until set.

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 a firm, sliceable structure.
- Molasses
- Provides the dark color, rich flavor and body of the filling.
- Sugar
- Adds sweetness and helps soften the set texture of the custard.
- Butter
- Adds richness and a smooth mouthfeel to the filling.
The step that matters
Baking until set. Eggs thicken as their proteins coagulate with heat. Removing the custard too early leaves it runny, while overbaking can make it curdle or turn spongy and weep.
Swap the nutmeg
How well each one fits the dish's main ingredients (molasses, sugar, butter, egg):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Allspicefits less well
Fit is the average pairing score against molasses, sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
