I have a recipe that requires whipped egg whites, but I want to substitute meringue powder and water. Do I actually whip the meringue powder, or do I just toss it in as is? Thanks!

usually a recipe called for whipped egg whites is using then to add lightness, volume and "fluff" to the mixture so it comes out less dense.

so, i'd whip the merenge powder just as if whipped egg whites. (you might also look in egg dept for egg whites in a little milk carton style box)

....what he said.

Thank you, I will.
