Thinly slice 2 scallions. Cook the scallion whites in butter in a saucepan with 6 cardamom pods, 2 fresh bay leaves, 2 star anise pods and 1 cinnamon stick until soft, 2 minutes. Stir in 1 cup basmati rice, then add 1 1/2 cups water and 3/4 teaspoon kosher salt. Bring to a boil, then reduce the heat to low, cover and cook until tender, about 17 minutes. Set aside, covered, 10 minutes. Top with the scallion greens and some chopped dill.
