Tossing the fresh blackberries in a tablespoon or two of flour helps to prevent the fruit from sinking to the bottom of the muffins. You need just enough flour to give the blackberries a light coating. Folding the flour-coated blackberries into the batter is the very last step, fold gently so you don't break the blackberries.
