Start by partially peeling the cucumber making stripes on it
Slice the cucumber into pieces about 1/4″ thick
Place the cucumber in a food processor and pulse until the cucumber is well-grated
Sprinkle the salt on the cucumber and give it a quick stir
Drain the moisture from the cucumber in one of two ways: Either place the cucumber in a mesh sieve over a bowl to let the moisture drain OR use a clean dish towel or cheesecloth to squeeze the moisture out of the cucumber
Meanwhile, in a medium mixing bowl, combine the garlic, vinegar, and olive oil
Add the grated cucumber to the garlic and stir to combine
Cover and store in the refrigerator until you are ready to serve the sauce
About 10 minutes before serving, remove the cucumber mixture from the refrigerator and stir in the yogurt
Sprinkle with fresh dill to garnish and serve immediately
