This is a lovely cool, refreshing Greek tzatziki dip that I first tasted and fell in love with in the Greek Islands. It is lovely with hot toasted pitta bread and veggies or lamb kebabs! The key is strain the liquid from the cucumber very well so the dip stays creamy and not watery and to ALWAYS use thick, full fat Greek yoghurt. Low fat versions won't cut it. Enjoy!
You can also add a tablespoon of chopped fresh mint, especially if you are having lamb, but I prefer to keep it simple and authentic and usually leave the mint out.
