Tzatziki is one of my favorite dips. If you have had it then you know what I mean. Anytime I order Greek food at a restaurant I always wants extra tzatziki (especially on a lamb gyro). This garlicky, cucumber Greek yogurt dip is ridiculously easy to make at home. The ingredients are few, but I have a couple of tips and suggestions to help you achieve the perfect tzatziki to satisfy your taste buds.
