this is eaxctly how I do it evrytime...... mix maybe 5-6 minutes
Watched it (with sound off)....I did try adding moisture to shortening in the past but was using my beater blade, which I have stopped now for icing. Also do you not use butter? Could the butter be putting air into my icing?
I"m going to try it again next week, with the correct beater...and I guess I'll make a bigger batch, I have a 6qt mixer. I know I mix my noncrusting like that, covering the beater, until its smooth....haven't had luck with the crusting and it does seem to bubble up "later" even if it seems smooth enough when I take it off the mixer.
