With Shrove Tuesday coming up next week, I'm craving Fastnacht Kuechle -- traditional German Lenten fried dough sprinkled with cinnamon sugar or confectioner sugar.... When they're done right, they're lighter and tastier than donuts. In Buffalo and probably other cities with a large German-American population, these are found everywhere during Lent. I miss them. Anyone know where I might find them in greater Boston?
