DNA Cocktail

Ingredients: American Style

60 ml fresh pineapple juice. This must be fresh as protease activity is required to degrade the histones associated with the DNA.
Blue curaçao1.
Lime juice and icing sugar, to decorate.

Also required:
A blender2
Large test tubes or boiling tubes, for serving.


Method:
Moisten the rim of a large test tube with lime juice then dip the rim into icing sugar.Add about 10 ml3 of blue curaçao to the tube.
Tilt the tube then with great care, pour about 20 ml3 of ice-cold gin down the side of the tube to form a layer above the blue curaçao.
Blend the strawberries and pineapple juice for 10 seconds, then drop the purée on top of the gin. Wisps of strawberry DNA will precipitate into the gin. More

England Style:

8 frozen strawberries (about 68 g) – the variety ‘Cambridge Favourite’ is naturally the most appropriate.
London dry gin – the strongest you can find. This is necessary to precipitate the DNA.N.B. Chill this gin in the freezer for at least 2 hours before preparing the drink.
