Ingredients
2 bunches of white seedless grapes
200 grams of white or red blackberries
2 tablespoons sugar
2 glasses of still mineral water
Preparation
Wash the fruit very well, remove from the branch grape by grape and separate the good grapes and discard the bad ones or if I opened any open, drain and dry the grapes and blackberries, use a clean canvas but not new, because if you like the purple or red blackberries, the juice from the same stains and does not come out, put the fruits in the blender together with the water and sugar, blend until a juice remains.
Put two long glasses with plenty of ice on a tray and serve the contents, put a long straw and enjoy.
