Whisk the flour, bicarbonate of soda, baking powder and salt together in a large bowl to combine. Then stir in the sugar, add all the dried fruit and nuts and mix together with your hands. Add the beaten eggs and mix thoroughly with either a rubber spatula or your hands (which will probably do the best job). Preheat the oven to 160°C/325°F/Gas mark 3. Grease and line two 20x10cm loaf tins (don't forget to grease the sides too). Divide the mix between the tins and put both of them on a low shelf in the oven and bake for 30-40 minutes.
When you take them out, the tops will be golden brown. Leave to cool in the pan.
Serve sliced very thinly with some cheddar.
