New Housewife New Terminology

I've been a newlywed for all of two months now.  I was never a big cook, I would try and fail.  Whether it be adding mozzarella cheese instead of parmesan in the fettuccine or burning the stove covers, something is always going wrong in my kitchen.  Today was no different, I have been taking a cake decorating class (which should show you right there, I really do try to be a better cook), we have to make our own icing and bring it to class.  This morning I'm in the kitchen slaving away, I have my mom's mixer a spinning when my brother walks in to inform me that my icing looks like mashed potatoes.  At that my husband walks in and reads the recipe.  "Did you use confectioner's sugar?" he asked.  "I dont know" I replied.  "I just used whatever sugar we had in the cabinet." With that he goes on to tell me that confectioner's sugar is powdered sugar. OK really? Really? Who came up with that name? Why can't you call it what it is? Powdered sugar.  Dont try to fancy it up and make it difficult to us new housewives.  We don't need the trade name just give us the generic name.  Oh the trails and errors of a young wife.  For now I guess I'll let my husband correct my ingredient mishaps,  but you better believe next time I read the words confectioner's sugar I will be grabbing for the right bag.
