If you have leftover egg whites, why not make them into a meringue and use them for panna cotta? They're very good with caramel sauce.You don't need an oven so they're quite easy to make.
I wanted to use up leftover egg whites and cream after I made soft egg custard. Besides the yolks, the ingredients you need are basically the same as what's required for panna cotta!
-Try to keep the ice water as cold as you can.
