Can you overbeat a meringue?
Correspondingly, what happens if you overbeat meringue?
Over-beating – It's possible to take it too far. After the stiff peak stage, egg whites will start to look grainy and dull. They will eventually collapse back on themselves. Whipped cream will also get grainy and will start to separate into fat and liquid.
Besides, how do you fix a meringue that won't stiffen?
Skipping the Cream of Tartar A mild acid will help give your meringue more volume and structure, which means they will inflate more fully and hold the air longer. You don't need much: about 1/4 teaspoon of cream of tartar for every two to three egg whites should do the trick. You can also use lemon juice.
Pasteurization heats the egg very quickly, then cools it to kill bacteria. Combine powdered egg whites with water and sugar, then beat. It may take longer to achieve the high, light texture of a good meringue with powdered whites. You can eat meringues made with pasteurized egg whites raw without risk of salmonella.
