Pineapple and cranberry fruit cake

Position the oven shelf just below the centre of the oven so that the cake will be central in the oven. Set the oven to cool gas mark 2 or 150°C. Beat together the butter and sugar until the mixture is light and fluffy, then gradually beat in the eggs, one at a time, adding a little flour with each egg. Fold in the remaining flour and mixed spice, then fold in the mixed fruit, pineapple and cranberries. Spoon the mixture into the lined cake tin and level the surface. Bake the cake in the centre of the oven 3-3½ hrs, or until a skewer comes out clean after being inserted into the cake. If the cake starts to brown too quickly then cover it with a sheet of baking parchment or foil and reduce the oven temperature slightly. When the cake is cooked remove it from the oven and leave it to cool for about 15 mins, then spoon over the rum. Leave the cake to cool completely in the tin. When the cake is cold remove it from the tin and wrap it in baking parchment then in foil.
