Verna's Cake Decorating Supply Store (next to the doughnut place) carried a product called Verna's Litex. It's a white powder that takes the excessive sweetness out of decorator's frosting. With the supply store closed and my carefully guarded supply dwindling, I am in a panic - and it seems like it's not available anywhere online. Has anyone heard of it/found a new source? I would appreciate any help...thanks.
