Pour the hot tea over the dried fruit and sugar, leave to soak overnight. Next day, heat the oven to 300oF Mark 2. Grease and line a 7 inch cake tin or two 1 lb loaf tins. Stir the egg, flour, spices and marmalade into the fruit, sugar and tea mixture. Pour into the tin or tins and bake for 1 1/2 2 hours, until firm to the touch and a skewer pushed into the cake comes out clean. DO NOT OPEN THE OVEN DURING THE FIRST HOUR OF BAKING TIME !!! This cake will keep well.
