What each ingredient does
- Strawberries
- Provide the fruit bulk, flavour, and natural pectin that helps the jam thicken and set.
- Granulated sugar
- Adds sweetness, helps the jam thicken and set, and preserves the fruit.
The step that matters
Adding the sugar. Sugar must be fully dissolved and the mixture kept at a steady boil so the pectin and sugar can form a gel. Too little cooking leaves the jam runny, while overcooking can make it stiff and dull in flavour.
