Mix 1 cup all-purpose flour, 6 tbsp sugar, 1/4 tsp baking powder, 1/4 tsp baking soda and a pinch of salt.
Stir into the dry ingredients until just mixed. Fold in 1/2 cup blueberries. Fill greased muffin tin 3/4 full. Bake at 350F for 20-22 minutes. Leave to cool in the tin for ten minutes before turning out onto a wire rack.
