Sorry if this has already been asked, but I couldn't find an answer.
I'm going to try it for the first time in a few weeks for a 5-year-old's birthday cake. It's an outdoor party, so I'm worried about if it will be "good" if it's not refrigerated since it does have milk in it.
Or can I substitute water for the milk?
TIA from a newbie!
Nope. I've never refrigerated it.
Milk and sugar stablize each other.
