Most recipes call for only the yolks and say to throw the egg whites away. Do not toss! It is a terrible waste! Instead, keep the whites and add them to dishes such as omelettes, steamed minced pork, porridge, tofu (coat before frying), fried rice etc Remember to omit or reduce the salt when cooking with the egg whites as they're naturally salty! (The whites are always saltier than the yolks)
