Can i substitute egg whites in for meringue powder?
Egg whites can substitute for meringue powder in terms of the effect. BUT, you are taking a risk using egg whites in a recipe that will not be cooked. Uncooked egg whites can give you food poisoning from Salmonella and other pathogens. You can typically find meringue powder, which has been treated to kill Salmonella and other bacteria, at hobby stores and cake decorating stores. Try “Michaels” or “JoAnn’s” cake decorating section for Wilton or other meringue powder. You can also order meringue powder at many on-line stores.
