Cream together the butter (125g) and sugars (90g soft light brown sugar, 85g soft dark brown sugar) until light and fluffy.
In a seperate bowl, lightly beat the egg (1 medium) to combine the yolk and white. Gradually beat the egg into the butter and sugar mixture, adding a little at a time.
Once all of the egg has been added, beat in the golden syrup (75g).
Add the flour (300g), ground ginger (3½ tsp), ground mixed spice (1 tsp) and salt (¼ tsp) and mix into the other ingredients. I start by using a wooden spoon and then bring the mixture together with my hands.
Wrap the gingerbread dough in clingfilm (or a reusuable wrap) and refrigerate for an hour (minimum).
Once the dough has chilled, pre-heat your oven to 200°C/180°C fan. Line 2-3 baking sheets with baking parchment or reusable baking liners.
Roll out the dough to roughly the thickness of a £1 coin and cut using your chosen cutter. Place each gingerbread man (or whatever shape you've opted for) onto the prepared baking sheet.If the dough is soft and sticky, refrigerate the biscuits for another hour (or 10 minutes in the freezer), otherwise bake immediately. Bake the biscuits for 8-10 minutes until they are golden around the edges, but still pale in the middle.
Remove the biscuits from the oven and move them to a wire rack to cool completely before decorating.
