1. Pour yogurt into a bowl and beat with a whisk or mixer for 4 minutes. 2. Wash cucumbers, dry, cut off the ends. Cut into thin strips and sprinkle with salt so that they give juice. 3. Peel the garlic and grind in a mortar along with half the walnuts into a homogeneous mass. Add to bowl with yogurt. Pour in sunflower oil and beat. Chop the remaining nuts into small pieces with a knife. Add cucumbers to the soup along with the secreted juice, nuts, finely chopped dill; salt and mix. Tip If the soup turned out to be very thick, it can be diluted with cold boiled water. In Bulgaria, a bowl of finely crushed ice is served separately with the tarator.
