A whole orange is boiled and puréed to make a rich marmalade-y cake which is lightly spiced and decorated with curls of orange rind. Add a little more spice if you want it to be very spicy.
Put the flour, almonds, raisins, walnuts, mixed spice and ... the tin and peel off the lining paper. Put the cake on a board or plate. To make the frosting, stir the cheese and orange zest together.
