Bubka is pure heaven to me - because it strikes the right note of sweet and bready. It is also relatively easy to make - not as complicated as true Danish with its rolled in blocks of butter but certainly richer and moister than a sweet dough. I have a few bubkas in my first cookbook, A Treasury of Jewish Holiday Baking (Doubleday, l998) where it sits like a queen of the realm of Jewish baking. Here it takes on another role - the diva of the yeasted, sweet pastries. I often use my bread machine to make the dough - although I have to give the mixing a hand at first by using a rubber spatula, just to get the rich dough properly going.
