What each ingredient does
- Blueberries
- Provide the main fruit, supplying flavour, colour and bulk for the preserved product.
- Sugar
- Sweetens the fruit and helps preserve its texture and flavour in the jars.
- Water
- Creates a syrup with the sugar, helping the berries cook evenly without scorching.
The step that matters
Turn the mixture into hot jars and seal immediately.. Filling hot product into hot jars and sealing right away helps create a vacuum seal and reduces the chance of spoilage from air and microbes.
