One of the best parts about traveling is the food. But that experience is usually bittersweet, at least as soon as you discover that you can’t find that food when you return, or find it offered in a different way than you remember it. During a recent trip to Vienna, dürüm and döner kebabs were those foods for me. Popularized in Europe by Turkish immigrants, a spit (similar to ones for gyros) is speared with lamb or chicken, which is then thinly shaved and quickly browned in a pan.
