Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Apple Jelly, with Soft Custard
Ingredients
Directions
Make the jelly
Cut the apples without removing the cores or skins and cover them with cold water.
Cook the apples over the fire until they can be strained.
Use 1 pint of the strained juice for every 1 pound of sugar.
Add a small piece of ginger-root and boil until it thickens slightly.
Once done, let it cool and place it in a deep dish.
Serve with custard
Pour soft custard around the jelly.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Their natural pectin helps the strained juice set into a jelly.
- Sugar
- Sweetens the jelly and helps it thicken as it boils down.
- Eggs
- Thicken the milk into a soft custard when gently heated.
- Milk
- Forms the base of the custard and provides creamy texture.
The step that matters
Boiling the juice with sugar until it thickens. Jelly sets only when enough sugar and pectin are concentrated by boiling. Too little boiling leaves it runny, while overboiling can make it stiff or sticky once cooled.
Swap the ginger
How well each one fits the dish's main ingredients (apple, sugar, milk, egg, vanilla):
- Cinnamonfits better
- Nutmegfits better
- Clovefits better
- Gingerthe original
Fit is the average pairing score against apple, sugar, milk, egg, vanilla. Candidates are from the same food group and used in at least 100 recipes.
