German cucumber salad (gurkensalat)

"Source a good apple cider vinegar for this recipe and many more great salad dressings. Chef Martin Boetz shares this easy summer salad based on his German grandmother’s recipe - he says it’s best served really cold from the fridge - the cucumbers crisp up and the dill, chives and parsley incorporate with the cream and sour cream." Maeve O'Meara, Food Safari Earth
