Ingredients:
250ml (1 cup) lightly-packed wisteria flowers
300g jam sugar (ie pectinated sugar)
500ml water
juice of 1/2 lemon
pinch of salt
Method:
Combine all the ingredients in a large pan, stirring until the sugar has completely dissolved.
Bring to a boil and continue boiling for about 10 minutes, or until the jam mixture reaches 105°C.
Pour into two small jars, that have been sterilized and warmed in a low oven (put a spoon in the jar to prevent cracking).
Stir the jam to ensure the petals are evenly distributed then divide between the jars.
Secure a lid, set aside to cool then label and store for a few days to mature before opening and using.
