Mix first five ingredients together, then stir in flours. Roll dough onto a lightly floured surface (about 1/4" thick). Spread with butter and sprinkle with remaining ingredients, except amaranth seeds. Toast seeds in a dry skillet until lightly browned. Roll up dough and slice 2 inches thick. Place on sides, close together in an oiled pan. Sprinkle with amaranth seeds, and bake at 350 F. for 30 to 40 minutes.
