Pre-heat the oven to 400 degrees Fahrenheit/Gas 6.
Place all the fruit in a large bowl and pour over the tea. Allow the tea to soak into the fruits for two hours.
Sieve the flour and spices into a large mixing bowl, and using your fingertips rub the butter into the flour.
Warm the milk in a saucepan. Place the yeast and sugar in a measuring jug (or small bowl) and slowly whisk in the warmed milk, followed by one of the beaten eggs.
Make a well in the center of the flour mixture and pour the yeast liquid into the well, gradually mixing in the flour from the sides using a wooden spoon. Stir in all the fruit and tea and mix well.
Sprinkle flour on a board and transfer the dough onto the board and knead gently adding more flour if needed (the dough should be smooth but not sticky).
Transfer the dough into a lightly oiled large bowl and cover with a tea towel or cling film and leave in a warm place until doubled in size (about an hour).
Once the barm brack has risen, tip out onto a floured board again and knead it back again and then shape into a greased 10-inch cake tin. Cover and leave it again in a warm place until it has risen (about an hour).
Once risen brush with the remaining beaten egg and place in the pre-heated oven for 40 minutes.
