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 ↓
Apple Custard
Ingredients
Directions
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apples
Peel the apples and remove the cores.
Place the apples in an enamel saucepan with 9 lumps of sugar and the juice of the lemon.
Cook until they become a pulp.
Make the custard
In a bowl, beat the eggs and mix with the flour and milk.
Add a small amount of grated nutmeg and the remaining sugar.
Pour the mixture into a double boiler over boiling water.
Stir until it begins to thicken, but do not let it boil.
Bake and serve
Place the cooked apples in a well-buttered pie dish, pour the custard over them, and bake in a 350°F (175°C) oven until the custard is set, ensuring it does not boil.
Serve hot or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Cook down to a pulp that forms the soft base under the custard.
- Eggs
- Set the custard as they cook, giving it body and structure.
- Milk
- Forms the liquid base of the custard and keeps it tender as it sets.
- Flour
- Thickens the custard and helps it hold its shape when cooked.
- Sugar
- Sweetens the apples and custard and balances the lemon's acidity.
The step that matters
Keep the custard below boiling. Egg proteins set gently at moderate heat. If the custard boils, the eggs scramble and curdle, leaving a grainy texture instead of a smooth, set custard.
Swap the apple
How well each one fits the dish's main ingredients (lemon, egg, milk, flour, sugar, nutmeg):

- Figfits better
- Applethe original
Fit is the average pairing score against lemon, egg, milk, flour, sugar, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
