Citrus bars
Crisp shortbread biscuit base with a creamy citrus curd baked onto the top
Heat oven to 200C/180C fan/gas 6. Lightly butter 2 large baking sheets. Put the flour, ¼ tsp salt, baking powder, bicarb and spices in a food processor. Add the diced butter and whizz until the mixture resembles breadcrumbs. Tip into a bowl and stir in the sugar.
Gently warm the golden syrup in a pan, add to the mixture and stir to form a dough. Roll the dough into 16 walnut-sized balls, then arrange, at least 2cm apart, on the baking sheets. Bake for 8-10 mins until golden. Cool on the trays before transferring to a wire rack.
