Put the dry ingredients, except the sugar, in a large mixing bowl. Mix the spices and flour together thoroughly.
Put the butter, sugar and syrup in a saucepan over a medium heat. Stir with a wooden spoon until the mixture has melted.
Pour the mixture into the dry ingredients and stir to combine.
Divide the dough into 18 balls and place 6 on each baking sheet. Place them about 10 cm or 3 inches apart to allow them to spread. Use the back of a fork or a glass to flatten the biscuits slightly.
Preheat the oven to 200 C / 400 F / 180 FAN / Gas 6 and bake for 8 to 10 minutes until golden brown.
Leave them to cool on the baking tray for 2 minutes then transfer to a wire rack to cool completely.
