Peel the cucumber and grate it. Place the grated cucumber in a towel set over a bowl. Add salt and 1 tablespoon of white wine vinegar or apple cider vinegar.

Squeeze the cucumber very well in the towel to remove as much moisture as possible. Put the yogurt in a bowl and add the cucumber and the remaining 2 tablespoons of vinegar.

Crush the garlic with olive oil in a mortar and add it to the yogurt. Finely chop the dill, add it to the yogurt, season with salt and pepper, and mix well. Serve with pita bread, fresh herbs, and a drizzle of olive oil.
