My Dad enjoyed this dessert as a young soldier shortly after WWII. For years he would ask for this dessert in restaurants only to be told that they were not familiar with the recipe. I found this recipe and made it for him for Father's Day this year, with great success. I decided to post it here so that I'll be able to find the recipe again, the next time Dad (or anyone else in my family) wants it. It is a light, lemony dessert - much like a souffle. I made it as listed below, except that I increased the lemon zest to the zest of a full large lemon. From the Time-Life book, Cooking of Vienna's Empire.
