Start by preheating your oven to 180°C. Line a baking sheet with some parchment paper and set it aside.
In a big bowl, mix the flour, sugar, spices and baking soda.
Add the eggs and knead, by hand, until all the flour-y patches are gone.
Add the dried fruit and nuts whole, then knead a little more by hand to have them all incorporated.
Dived the dough in 4 and roll the logs so that you have a sausage of roughly 30cm.
Place each long on the tray, leaving enough space for the logs to rise and spread, and bake for 25-30 minutes or until golden and puffy.
Transfer the logs to a cooling rack and drop the oven temperature to 140°C.
When the logs are cool enough to handle, cut them diagonally using a serrated bread knife in 1cm thick slices.
Place all the slices flat on the baking trays and bake for 15 minutes, then turn each slice and bake for a further 15 minutes.
Let them cool down completely on a cooling rack.
