Place the blueberries in a saucepan with the Siucra sure set jam sugar, lavender, nutmeg and vanilla pod as well as the lemon zest and juice.
Bring to the boil, ensuring that the sugar dissolves first and reduce the heat, simmer gently until soft, stirring from time to time.
Boil until setting point is reached (104 °C). If you do not have a jam thermometer, place a saucer in the freezer. Check the setting point every 10 minutes but it may take up to half an hour.
Take the saucer out of the freezer, place a teaspoon of jam onto the saucer, leave it for a few seconds and then push it with your finger, if it wrinkles then it has reached setting point.
Leave to cool slightly, remove the vanilla pod and ladle into sterilised jars.
Seal, label and store in a dark cool place.
Catherine’s Tip: for a lighter lavender flavor, place the lavender in a muslin bag and remove before potting the jam.
