i'm out of merange powder is there anything else i can use. Thank you

The old recipes used egg white instead. Of course some people would say it's not safe because of eating raw egg so it would really be a judgement call on your part. The egg white would replace meringue powder and water.

egg white, of course.

ok thank you i just wanted it for practice now another question, how many egg whites, for the 31/2 cup yield

I never put MP in my practice recipes.

ok thanks so much

i made the royal icing but i had to add a ton of con sugar it was good for making swirls, dots, and tear drops, but i was sure when i used it before i tried to make a rose like a buttercream rose but it wouldn't work this time , could i have used something else last time i was making a crown. thankis all

It sounds like you didn't beat the icing long enough. It needs to beat for 7 to 10 minutes (maybe only 4-5 minutes if it is a KA mixer).
