I have a royal frosting recipe calling for uncooked raw eggwhites? Is this safe?
Yes, it is safe. You can also buy pasteurized raw egg whites in the dairy aisle, and pasteurized powdered egg whites in the baking aisle (which is what I usually use for royal frosting.)
hardlikearmour is a trusted home cook.
You can also heat the egg whites prior as recommended by the American Egg Board:
Cooking Egg Whites for Use in Recipes – Cooking egg whites before use in all recipes is recommended for full safety. The following method can be used with any number of whites and works for chilled desserts as well as Seven-Minute Frosting, Royal Icing and other frosting recipes calling for raw egg whites.
In a heavy saucepan, the top of a double boiler or a metal bowl placed over water in a saucepan, stir together the egg whites and sugar from the recipe (at least 2 tablespoons sugar per white), water (1 teaspoon per white) and cream of tartar (1/8 teaspoon per each 2 whites). Cook over low heat or simmering water, beating constantly with a portable mixer at low speed, until the whites reach 160° F. Pour into a large bowl. Beat on high speed until the whites stand in soft peaks. Proceed with the recipe.
Note that you must use sugar to keep the whites from coagulating too rapidly. Test with a thermometer as there is no visual clue to doneness. If you use an unlined aluminum saucepan, eliminate the cream of tartar or the two will react and create an unattractive gray meringue.
