What each ingredient does
- Strawberries
- Provide the fruit, pectin and flavour that form the jam's body and taste.
- Sugar
- Sweetens the jam and helps it set and keep its texture as it thickens.
The step that matters
Stirring during the first 30 minutes of boiling. Frequent stirring keeps the crushed berries from scorching on the bottom of the kettle while they break down and thicken. Scorched sugar and fruit give a burnt flavour that cannot be removed later.
