Poppy Seed Rolls-a Mennonite Tradition

Gotta find the recipe!  Really unique, Mennonite dessert from the Kansas heartland.  Mennonite families use so many poppy seeds for these and other items, that they grow their own, a tradition for many years, I am sure, going back to when they farmed in Russia, Prussia, Poland, Holland and other countries that they immigrated from.  These rolls use a sweet dough that is rolled out as if making cinnamon rolls.  A cooked, sweet mixture of poppy seeds and sugar is spread over the dough, then it is rolled up like a jelly roll.  Let it rise like this, then bake.  It can be baked and frozen until needed for special occasions.  When done, just slice off pieces of the roll.  It is sooooooo good!
