I have a customer that has asked for a not-so-sweet icing. I don't know of any icing that isn't so sweet. Can anyone recommend a recipe that I can try? I need for cake to be able to be UNrefrigerated. I'm lost on this one.

I know this topic has probably been covered before, but I can not find the threads. If you know where I could the thread, please let me know.

TIA

Couldn't you just add more salt? I also add flour and cornstarch to help it remain thick while not being overly sweet. Helps fight humidity as well.

Have you tried Italian Meringue Buttercream (IMBC)? My family thinks any icing make with powdered sugar tastes "too sweet" to them. But, they really like the IMBC. (I use Shirley W's recipe in the recipes here at CC.)

You also could try Swiss Meringue Buttercream (SMBC). If I'm remembering correctly, jkalman had a recent tutorial thread with photos. You might search by "IMBC" or "SMBC."
