Sugar-Free Black Widow Cocktail

Step 1Place the blackberries in a saucepan. Add the lime juice and water. Bring to a boil over a medium heat. Boil for 3-5 minutes.

Step 2Once softened, mash the blackberries using a fork. Pour through a fine mesh sieve and using a spoon, press the blackberries through so that only the skins and seeds remain in the sieve.

Step 3Pour into a jar. The juice should be quite thick, the consistency of syrup.
Note: This recipe makes about 2 ¹/₄ cups (530 ml/ 18 fl oz) of blackberry syrup. This will be enough for 6 cocktails.

Step 4Add the powdered sweetener and mix until combined. Let it cool and refrigerate until ready. The syrup can be stored in the fridge in a sealed bottle or jar for up to a week.

Step 5To serve, optionally decorate your cocktail glasses by dipping the rims in water and then in a mixture of acai powder (or any berry powder). Fill each glass with ice and pour in the vodka.

Step 6Add the sweetened blackberry juice.

Step 7Decorate with more fresh blackberries or mint leaves and serve.
