Just back from 3 weeks in Greece and had tzatziki at least once a day. Loved theirs. I can't get the same richness, sweetness and mouth feel that I had in Greece. I am using a 0% Skotidakis brand Greek Yogurt that is made in Eugene, Ontario and like it better than the available Liberte as it is richer in taste and thicker. I am almost 100% sure that I have to use a full fat Greek yogurt to get that great taste. I would prefer staying with a lower fat yogurt as we eat a lot of it. My question....would EVO, a tbsp. or 2, help to add the "fat dimension"? Or is there anything else to add for flavour other than the grated cucumber, garlic, dill/mint, and some lemon juice?
