Once the starter is ready, add the remaining 375 g (13.2 oz) of flour, the rest of the sugar, the softened butter, the egg, the lemon zest, the cinnamon, and optionally the mixed spice blend..
Knead at speed 1 for 4 minutes, then at speed 2 for 10 minutes. If kneading by hand, count the same time. You should obtain a soft, non-sticky dough that perfectly detaches from the sides of the bowl.
During kneading, drain the raisins and cranberries well, then mix them with the other dried fruits and candied fruits.
Add them to the dough and knead for 1 minute to incorporate them well.
Note: After testing the addition of the dried and candied fruit mixture before and after rising, it turns out that adding them after rising prevents the dough from tearing on the surface. However, nothing serious as you can see in the photos. Adopt what you prefer.
Turn the dough out onto the work surface and flatten it into a square with the palm of your hand. Make sure the dried fruits are well distributed. If not, fold and roll out the dough several times until the fruits are evenly distributed. Then gather the dough into a ball.
Place the dough in the bowl then cover it with plastic film and a cloth.
Let rise in a draft-free place for 1 hour 30 minutes or more, until the dough has doubled in volume.
Note: In cold weather, place the bowl in an oven preheated to 30°C (86°F) and turned off, or place a bowl of hot water at the bottom of the oven.
