Note: Dried egg whites are pasteurized so this product is a wise choice in dishes that call for an uncooked meringue. They are also convenient in recipes calling for egg whites because there is no waste. Look for brands like Just Whites in the baking or natural-foods section of most supermarkets or online at bakerscatalogue.com.
