Raw egg whites, they're all the rage, or at least I think so. Two Chicks sell free range egg whites ($6.50), which I think is one of the most wonderful things I've yet to find.
Firstly, they're incredibly convenient: the carton contains 15 egg whites which makes everything so much easier when I'm trying to make meringues.
They're also great for your diet. If your following a low-fat, high protein diet, which seems to be popular these days, they are fantastic because they're naturally high in protein and you don't have to worry about seperating egg-yolks from the whites yourself.
More than anything it's a major time-saver. I often struggle to seperate egg whites from the yolks with ease, but with this product, it's an absolute joy to make an egg-white omelette, or use egg whites in cakes - it's fantastic.
Buy a carton from WholeFoods, it's definitely worth it's weight in eggs.
