1. Chill the Glass

Chill your martini glasses in the freezer for at least 30 minutes. This ensures the cocktail stays cold longer and enhances its presentation.

2. Mix the Ingredients

Combine 2 oz of vodka (or white rum), 1 oz of black raspberry liqueur, and ½ oz of fresh lime juice in a shaker filled with ice. Shake vigorously for about 15 seconds to blend the ingredients.

3. Strain and Serve

Strain the mixture into a chilled martini glass. Slowly pour a splash of grenadine down the back of a spoon to create a settled red layer at the bottom, resembling a bubbling cauldron.

4. Garnish

Garnish the martini with a rosemary sprig, resembling a witches’ broom, and add two blackberries for a spooky effect.
