Add ice, blackberries, and orange slices to a cocktail shaker. Squeeze in juice of 1/2 orange. Shake. Remove lid of shaker. Take your serving glass and insert it upside down into the shaker. Holding both the shaker and serving glass together tightly, turn it upside down so that the cocktail pours out into the serving glass. Top with Stella Rosa Black and garnish with an usual-looking rambutan fruit.
