I know alot of people use merengue (sp?) powder but I do not have any atm. If I use egg whites (its not to eat but to practice flowers) will it spoil if I store it properly at room temperature. I ask this because I was doing some research online and it seems alot of people for some reason say to not store royal icing in the fridge. Im just not sure if with the egg whites it will go bad or not. TIA!
