A year and several days on, and I finally work out how to microwave a package of eggwhites.
(Slightly excused by the fact that we've only had packaged eggwhites on shop shelves here for a few months to my knowledge, and even then I've only seen them in Selfridges and Wholefoods).
Yes, prior to this, if I've been eating eggwhites I've been hard-boiling eggs and burning my fingers separating them out. It hasn't encouraged me to use them often. This 500g package though, after 10 mins in the microwave in my lasagne dish, has cut up into little cubes like tofu or quorn - far more appetizing than scraps with shell.
So, that's me sorted for protein for the next few days then.
