Preheat the oven to 425°. Soak the dried cherries in hot water until plump, about 10 minutes. In a large bowl, whisk the flour with the sugar, baking powder, cardamom and salt. Drain the dried cherries and pat dry. Add them to the dry ingredients along with the cream and stir until the dough is evenly moistened. Gather the dough into a ball and gently knead it 4 or 5 times.
