In a large mixing bowl, combine the flour, baking powder and salt.
Dice the butter into small 1/2 inch cubes then blend it into the flour using a pastry cutter until the mixture resembles small peas. Place the mixture in the freezer for five minutes.
Dice the pear finely. Set aside 2 tbsp of the whipping cream. Finely chop the Rosemary.
Add the pear, the remaining cream, the asiago cheese and rosemary to the flour mixture. Using a wooden spoon stir the mixture just enough to bring it together.
Tip the dough out onto waxed paper and shape into a 7 inch round. It will be a bit crumbly. Ct the round into 8 wedges and place the wedges on a lightly greased baking sheet, keeping them a little apart.
Brush the tops with the reserved 2 tablespoons of cream and bake for 15 minutes.
