  2. Add 1 tablespoon of sugar for flavoring and boil for 20 minutes.

  3. Remove from heat, cover, and let it stand overnight.

Set and seal

  1. If not firm enough, reheat to boiling and cook for 10-15 minutes.

  2. Seal in jars.

  3. If still not firm, place in sunlight to thicken.

    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

Juice of sweet apples
Provides the pectin and fruit flavor that set the jelly as the liquid reduces.
Sugar
Adds sweetness and flavor and helps the jelly hold its set.

The step that matters

Reducing the juice to one quarter. Jelly sets only when enough water evaporates to concentrate the pectin and sugar. Stopping early leaves a runny result, which is why the record suggests reheating if it is not firm.
