What each ingredient does

Strawberries
Provide the fruit flavor and body that the jam is built around.
Loaf sugar
Sweetens the jam and helps it set into a spreadable gel as it boils.
Red currant juice
Adds extra fruit flavor and natural pectin to help the jam set.

The step that matters

Boiling with the sugar until it sets. Sugar must be boiled hard enough to concentrate the mixture and reach the gel point. Stopping too early leaves a runny jam, while boiling too long can darken and dull the flavor.
