How to Make It
To prepare dough, dissolve yeast in warm water in a small bowl; let stand 5 minutes.
Combine sour cream and next 5 ingredients (through egg) in a large bowl, stirring until well blended. Gradually stir yeast mixture into sour cream mixture. Lightly spoon 2 1/3 cups flour into dry measuring cups; level with a knife. Add 2 cups flour to sour cream mixture, stirring to form a soft dough.
Turn dough out onto a lightly floured surface. Knead until smooth and elastic (about 8 minutes); add enough of remaining flour, 1 tablespoon at a time, to prevent dough from sticking to hands (dough will feel slightly tacky).
Place dough in a large bowl coated with cooking spray, turning to coat top. Cover and let rise in a warm place (85°), free from drafts, 1 hour or until doubled in size. (Gently press two fingers into dough. If indentation remains, dough has risen enough.)
To prepare filling, combine brown sugar, rind, and cardamom. Divide dough into two equal portions. Working with 1 portion at a time, roll dough into a 12 x 10–inch rectangle; brush with 1 tablespoon butter. Sprinkle half of filling over dough. Beginning with a long side, roll up jelly-roll fashion; pinch seam to seal (do not seal ends of roll). Repeat procedure with remaining dough, 1 tablespoon butter, and filling. Cut each roll into 12 (1-inch) slices. Place slices, cut sides up, in a 13 x 9–inch baking pan coated with cooking spray. Cover and let rise 30 minutes or until doubled in size.
Preheat oven to 350°.
Uncover dough. Bake at 350° for 25 minutes or until lightly browned. Cool in pan 5 minutes on a wire rack.
To prepare glaze, combine powdered sugar and juice, stirring until smooth. Drizzle glaze over warm rolls.
