There are many versions of this recipe, some use yeast and others use baking powder. This is my Gran's recipe which I've tweaked a bit, and it's very easy to make.
450g/1lb dried mixed fruit
250g/9oz brown sugar
300ml/½ pint warm black tea [I used a Breakfast tea]
2 tsp mixed spice
450g/1lb self-raising flour
1 egg beaten.
In a large bowl soak the fruit and sugar in strained tea and leave overnight.
Next day preheat the oven to 170C/Gas 3.
Line a 900g/2lb loaf tin with baking parchment.
Mix the remaining ingredients into the fruit mixture and beat well. The mixture will be soft and runny. Pour into the loaf tin and bake for 1½ hours or until a skewer inserted into the middle comes out clean.
Serve sliced and buttered.
