Preaheat oven to 180. Place the polenta, flour, baking powder, bicarbonate of soda (baking soda), sage, salt, pepper, cream and eggs in a bowl and mix well to combine. Place extra sage in the bases of 12 lightly greased 1/2 cup capacity (125 ml) muffin tins. Line each tin with prosciutto and fill with polenta mixture. Bake for 15-20 minutes or until cooked. Turn out to serve. Makes 12
Note
I could not find instant polenta so I used semolina flour instead. That worked fine, so if you have no polenta use that. I also made a batch with cornflour and that worked as well although the batter and the final cakes were a littl drier then the one with semolina. I would use a bit more fluids if you bake with the cornflour.
