caster sugar and 250ml/9fl oz lukewarm water in a large bowl. Leave to stand for 10 minutes until the mixture is frothy.
Add the flour and butter and mix thoroughly. Tip onto a lightly floured surface and knead for about five minutes to form a smooth elastic dough.
Place the dough into a clean
lightly oiled bowl and cover with a damp tea towel. Leave to prove in a warm place for about one hour or until doubled in size.
When the dough has risen
remove the tea towel and punch the dough down. Tip onto a lightly floured surface and knead in the fruit and muscovado sugar until well combined.
Shape the dough into a round shape and place on a lightly greased baking sheet. Cover again with a damp tea towel and leave to rise in a warm place again for 30 minutes or until it has doubled in size.
Preheat the oven to 180C/350F/Gas 4.
