Preheat the oven to 190°C. Sift the ﬂour, bicarbonate of soda, salt, ginger and spice into a bowl. Stir in the rice flour, rub in the butter and mix in the sugar. Warm the syrup and stir it in, then knead lightly in the bowl to form a smooth dough. Shape the dough into walnut-size balls and space well apart on greased baking trays. Bake each batch for 10–12 minutes, or until they are golden. Cool on the baking trays for 5 minutes, then transfer to a wire rack to cool completely.
Cream sugar, egg, salt and butter together. Add flour, bicarbonate of soda and spices. Mix well. Roll teaspoonfuls of dough into balls and roll the balls in extra sugar.
