Chilled Cucumber and Orange Juice with Oregano

Moroccans love fresh juices, and the combinations they make are eclectic and highly seasonal. This is one of my favorites. Although it is commonly prepared as a juice, it can also be a drinkable dessert, especially on warm summer days. I once had it as a "salad" served with a spoon in late fall in the eastern High Atlas. Oranges hadn't yet ripened, and instead the cook used small clementines from down the valley. Served before a communal platter of Berber Barley Couscous with Vegetables, the drink seemed closer to a light, sophisticated, vibrant green gazpacho than a rustic salad.
