Ajo blanco con uvas (Cold garlic soup with grapes)

This is another local, southern dish which is refreshing in summer. Any type of grapes will do, local Moscatel being very nice.

250 g breadcrumbs.
150 g raw almonds, crushed
2 cloves garlic, without shoots
1 egg
2 tablespoons vinegar
1 glass olive oil, maximum acidity 0.4º
1/2 litre water
100 g grapes
50 g currants and salt

Soak the breadcrumbs for one hour and then strain. Crush all the ingredients in a blender for 5 minutes and then in a food mill. Place the mixture in the refrigerator to cool. If the mixture is too thick, add ice or more water. Garnish with grapes and currants.
