Add your plain yogurt to a large square of cheese cloth and tie it up with twine (like a large satchel). Tie the twine to your kitchen faucet and let it strain. Wait 2 hours. (See photos above.)
While waititng, grate your cucumber and use thick paper towels to squeeze out as much of the juice as possible.
Add your cucumbers, minced garlic, lemon juice, salt, and sour cream to another bowl and mix well. Store it in the fridge until your yogurt is ready,
When your yogurt is nice and thick, remove it from the cheese cloth and add it to your sour cream mixture and mix again. Allow to chill in the fridge until ready to eat.
Serve with pita triangles or veggies.
Straining your yogurt is the most important thing!Feel free to add freshly chopped dill or parsley, or dried oregano for more flavor!You can use red wine vinegar instead of lemon juice if you don't have it.
