If you're hosting a Halloween cocktail party, add this drink to the menu. Cherry juice makes this deadly-looking cocktail taste sweeter than it appears, and black vodka creates the bewitching black hue.
Combine ice, vodka, and cherry juice in a cocktail shaker; shake vigorously. Pour into a martini glass. Thread raspberries and blueberries onto a cocktail skewer, and place in drink. Serve immediately.
