Donut page: Hi,
Hope you are doing well.
I am facing problem in storage of donut glaze. I use powdered sugar, water and vanilla extract in my glaze. When I store it in a stainless steel bin, after a day or two the very bottom begins to harden. The top 4 or 5 inches stays good, but over time an inch or two or hard sugar forms at the bottom. I am looking for an easy additive to my glaze that would not alter the taste, but prevent it from getting hardened.
