Hey everyone! Is there a trick you use or special ingredient for your royal icing to dry shiny? I've tried adding a couple tablespoons of corn syrup towards the end of my mixing but is there a better way, time or something else altogether? Sometimes I feel the color dries a little flat or a little too matte. Thanks in advance! I've got a big cookie order coming up and I'd love to impress the pants outta them! LOL.
