What each ingredient does

Grape juice: Forms the cooking liquid; reducing it concentrates its sugars and flavor, sweetening the preserve.
Fruit: Provides the bulk and texture of the preserve, softening and turning clear as it simmers in the juice.

The step that matters

Boil gently until the fruit is clear and tender. A gentle simmer lets the fruit soften evenly and absorb the concentrated juice without breaking apart. Vigorous boiling can turn pieces mushy and cloud the syrup.
