Step 1

Start by placing your ingredients in your saucepan - all can go in at the same time. Place this over a medium heat, stirring occasionally until the sugar dissolves.

Step 2

Once your sugar has dissolved (about 5 minutes), turn the heat up slightly and allow to boil.

Step 3

Boil for about 5-10 minutes, stirring occasionally, to ensure that the berries aren't becoming stuck on the bottom of the pan and burning. See tips below for info on the length of boiling.

Step 4

Strain through a fine meshed sieve to remove the vanilla pod and pulp, leaving you with a smooth vibrant purple simple syrup.

Step 5

Allow to cool and store in the fridge. Length of chilling will depend on intended use - if aiming for a chilled cocktail, it's best to leave for a couple of hours to get thoroughly cool.
