What each ingredient does

Strawberries
Provide the fruit flavour, colour and pectin-bearing body that the jam is built on.
Sugar
Sweetens the jam and helps it set into a spreadable gel while preserving it.

The step that matters

Boiling to the desired consistency. Jam sets as the mixture cooks down and concentrates, so stopping too early leaves it runny and cooking too long can make it stiff or caramelised. Judging the point by sight or a set test matters.
