Preheat the oven to 200ºC/400ºF/gas 6. In a food processor, blitz the sultanas, apricots, dates, baking powder and a little of the flour (just enough to stop the fruit sticking to the blades). If you don’t have a food processor, you can chop it very finely. Put this mixture into a bowl with the muscovado sugar, the golden syrup, the egg and the melted butter and stir together. Then add the very hot water and the remaining flour and mix well with a whisk. Divide the mixture between 12 cupcake papers (I like to double up the papers to give the mixture a bit more hold) and place on a baking tray. Bake in the preheated oven for about 15 minutes.
