Stretch the cost of blueberries by making them into jam with an apple. There's no loss of flavour and the jam has a delightful texture.

Ingredients

• 1 green apple, peeled and cored
• 500 grams blueberries, fresh or frozen
• ¼ cup lemon juice
• 750 grams sugar

Method

1. Thinly slice the apple and place into a large heavy-based saucepan or jam pan with the blueberries and lemon juice.
2. Cook over a low heat, stirring occasionally, until the apples and blueberries soften.
3. Bring the fruit to the boil and gradually stir in the sugar, stirring until the sugar has dissolved.
4. Bring to the boil and boil rapidly for 8 minutes before testing. Make sure you remove the jam from the heat each time you test for setting. Boil until the jam will give a set. (See Allyson's guide to making jam).
5. Remove from the heat, allow the bubbles to subside and skim off any scum.
6. Bottle into hot, dry, sterilised jars. Cover with a towel and leave until cold. Seal and label.
