I guess it has been almost 20 years since I worked at Zorba's restaurant in Fort Worth. Zorba's had the BEST gyros I have ever had. Zorba's in the North Hills Mall is gone now. The North Hills Mall is even gone now. But I think I have a little treasure from the past that you are going to love. Gyros that you get at a stand or restaurant usually have the same basic ingredients. Pita bread, gyro meat (probably a cone from Kronos), onions, and tomatoes. This is all turned into an unbelievable delicacy with a strange condiment called "tzatziki sauce." There are lots of tzatziki sauce recipes on the Internet. But they don't quite match the creaminess of the tzatziki from Zorba's. I also see tzatziki sauce recipes with dill, mint, lemon juice, and other strange things in them. None of that was in Zorba's tzatziki. Now, I have to admit that they never showed me how to make the tzatziki. That was all done by Tula in the back kitchen. Tzatziki was a complete mystery to me the whole time I worked there. But I did happen to see the two things that made their tzatziki so special. I remembered that one of the ingredients was sour cream. Another one of the ingredients was something that sounded similar to sour cream, but it was different. It was something I had never heard of before. Years later, I kept thinking "what was that other ingredient? Sour...something?" Now that we have the Internet, I am able to put together the last piece of the puzzle. It was not "sour...something." It was "something...cream." It was, in fact, yogurt cream. Now I can give you the basic ingredients so that you can make this simple and extraordinary tzatziki sauce.
