300 ml cream (35-40% fat content)
300 ml golden syrup
700 g granulated sugar
2 tsp cinnamon, ground
1,5 tsp cloves, ground
1 tsp cardamom, ground
1/2 tsp bitter orange peel, ground
2 tsp ginger, ground
1,5 tbsp baking soda
1 kg flour

Mix cream, golden syrup and sugar in the bowl of a stand mixer, or stir together by hand. Add all the spices and the baking soda, along with half of the flour. Gradually add the rest of the flour until you have a nice, supple dough that's not too tacky. Divide into six logs, and place each in a plastic bag or plastic wrap. Keep in the fridge for at least a few days, but preferrably a week.

Roll out and cut into desired shapes, and bake at 160°C for 8-10 minutes. (8 was perfect in my convection oven, for fairly small cookies.)
