How to make the D.N.A. Cocktail – Freeze the Strawberries and chill the Gin and blue Curacao. Use a test tube or if not available, a Shot Glass. Moisten the rim with Lime Juice, then dip the rim into icing Sugar. Add blue Curacao. Tilt the tube/glass with great care, then pour chilled Gin down the side to form a layer above the blue Curacao. PurA(C)e the Strawberries and Pineapple Juice in a bar blender for 10 seconds, then add the purA(C)e on top of the Gin. Wisps of Strawberry D.N.A. will precipitate down into the drink.
