What each ingredient does

Citric acid
Adds acidity, which brightens the flavour and helps the fruit keep its character.
Ripe strawberries
Provide the fruit flavour and most of the body of the preserves.
Fine sugar
Sweetens the preserves and helps preserve them by binding water.

The step that matters

Boil the drained liquid gently for 3 to 4 minutes with the sugar. Boiling gently dissolves the sugar fully and concentrates the liquid without scorching it. Cooling completely before bottling matters because warm syrup can build condensation and spoil.
