well the best are pavlova or meringue. but you can also just add the extra whites into your next scrambled eggs or omelet.

I also agree with meringues and sweet treats.

Ohhhh, they are the handiest things to have left.
Super healthy…start your day with an egg white omelette
Lemon meringue pie
Little meringues (cook them and top with a scoop of cream and berry and a syrup)
Pavlova

Egg white can be fried and then used in other recipes such as fried rice and even in salads.

You can make an Angel Food Cake. I looked here in Mouths of Mums, but I couldn’t find a recipe. Look for example at this one http://www.marthastewart.com/341215/angel-food-cake by Martha Stewart.

You can add egg whites to anything what you cook or bake. Beautiful to add in soup or a sauce, perfect in your cakes, meringue, cookies,or pies, easy to add in your mince meat and so on. I remember my mum making a desert from egg whites, it was called “Haagse bluf” (original Dutch recipe) and it’s 2 egg whites mixed with 200 ml berry juice and 200 gm sugar (optional) mixed together till stiff.

Make an egg white omelette. Beat them up and make a face mask out of them. Put a meringue topping on something, poached fruit fir example

You can whip up meringues as all you need are egg whites and sugar. There should recipes including a lemon meringue cake which is my favourite or a pavalova which I have made successfully a few times . You just need to be patient in making them and not rush otherwise it won’t turn out well. Good luck .
