Low-Carb Black Widow Cocktail

Step 1Place the blackberries in a saucepan.

Step 2Add the lime juice and water. Bring to a boil over a medium heat. Boil for 3-5 minutes.

Step 3Once softened, mash the blackberries using a fork.

Step 4Pour 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 5Pour into a jar. The juice should be quite thick, almost the consistency of syrup.
Note: this recipe makes about 2 ¹/₄ cups (530 ml/ 18 fl oz) blackberry juice. This will be enough for 6 cocktails.

Step 6Add the powdered Erythritol and mix until combined. Let it cool and refrigerate until ready. The juice will keep refrigerated for up to 5 days.

Step 7To 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 8Add the sweetened blackberry juice.

Step 9Decorate with more fresh blackberries or mint leaves and serve.
