Preheat oven to 375° F. In a large mixing bowl, combine flour, baking powder, salt, and sugars. Mix well. Cut in the butter and shortening. Stir and fluff in the dried berries.
In a separate bowl, combine cream, egg, and jelly (if using), mixing well. Fold into dry ingredients and mix just until moistened. Turn dough out onto a floured surface. Pat into a circle and score wedges, or cut into biscuit-size rounds. Bake no longer than 15 minutes! Transfer immediately onto cooling rack, or bake on grid baking sheet to keep bottoms from over-browning.
Yield: 8 scones
