Actually I have some problems with recipe normal cocktail with my new liqueur DeKuyper Blueberry… But result is great!
50 ml vodka
25 ml blueberry liqueur (white)
1 dash blue curacao
2 drops of grenadine
Shake well and strain into frozen cocktail glass.
I use BOLS Blue and Lemon-X grenadine for color like blueberry. This cocktail has strong, sweet berry taste. Admirable!
