For the raspberry jam with spirit, sort and clean the raspberries well. If possible, please do not wash them.
Mix the fruit in a large pot with the jam sugar and leave to infuse for about 1 hour.
Remove the zest from the lemon and squeeze out the juice.
Add both to the fruit.
Then bring the mixture to a boil and boil for 4 minutes until bubbling.
Add the raspberry brandy and bring to the boil again.
Immediately fill the hot raspberry jam with spirit into clean jars and seal well.
