Remove all the berries from the stalks using a fork. Pick out all small stalks and remove any other debris
Simmer the berries with water (2:1 ratio of berries to water) for roughly 20 minutes occasionally mashing them with a potato masher
Using a fine mesh sieve, allow the juice to drip through until a bowl
Next, for every 500ml of liquid, you need to add 250g of sugar. Add both of these to the saucepan, along with a couple of slices of lemon and a couple of slices of orange. Also, add your spices.
Simmer for about 20 minutes
Use a funnel to decant the syrup into a sterilised bottle using the sieve to remove fruit and spices.
