I've heard of adding the tonic water only to the icing mixture and then there's a method of using the tonic water and jello then dip the cupcakes in that mixture...what's best? I would like to color the icings in neon colors for this birthday cupcake order I have....does anyone have any suggestions? Has anyone tried both methods and if so, which one works best??? Thanks in advance for your help :)
I've read that the tonic water gives it a sour taste.
