I'm posting this recipe to demonstrate an effective method of making a wet/enriched dough using an electronic stand mixer (i.e. kitchenaid or kenwood). The key step is to make a 'standard' dough which will kneed effectively in the mixer, then let it rest for 30 minutes then add further wet ingredients (i.e. in this case butter, but water could also be used). You can play around with different flavours, for example try a chocolate brioche loaf by substituting the soaked dried fruit for chocolate. This recipe is for two loaves (which does border on testing the capacity of some stand mixers), needless to say you can halve the ingredients to make one loaf.
