Ingredients
Directions
Prepare the fruit
Prepare the fruit by peeling, coring, and slicing as needed.
Cook the prepared fruit with enough water to boil.
Make the jam
Add sugar in a ratio of 1:1 or 1:2 (sugar to fruit) based on preference.
For jelly, cook the fruit in a small amount of water until soft, then strain the juice.
Evaporate the juice with sugar until it reaches a density of 30° to 32° Be.
Store
Pour the hot jelly into tumblers for storage.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Shared aroma: beta-damascenone (apple, rose).
Apple and sugar barely smell alike, yet cooks put them together in 16,478 recipes: they work on texture and structure more than aroma.

What each ingredient does
- Fruit
- Provides the main flavour, body and natural pectin that help the jam set.
- Pure cane sugar
- Sweetens and thickens the fruit while helping it set and keep.
The step that matters
Evaporating the juice to density. Sugar and fruit must be boiled down to the target density so the sugar concentration and pectin allow the jelly to set. Too little cooking leaves it runny, while overcooking can make it stiff and sticky.
