Put the sultanas, raisins, currants and cherries
in a bowl with the brandy and soak overnight.
Preheat the oven to 150°C/300°F/Gas mark 2.
Lightly grease and line a deep 23cm/9in round
cake tin.
Beat the butter and sugar in a large
bowl with an electric beater to just combine.
Beat in the jam, treacle and lemon zest. Add the
eggs, one at a time, beating after each
addition.
Stir the fruit, flour and spices
alternately into the mixture. Spoon into the tin
and smooth the surface.
Tap the tin on the bench
to remove any air bubbles. Level the surface
with wet hands. Bake for 3 to 3 1/4 hours.
Brush
the surface with the extra tablespoon of brandy.
Cover the top of the cake with baking parchment
and wrap in a tea towel. Cool
completely
in the tin.
