Back in the early days of learning how to cook, I, like anyone, made a lot of stupid mistakes. One of the silliest mistakes I made was using part of an ingredient and then throwing away the other part(s) that I wasn't using. Case in point: eggs. Whenever I would make a recipe that called for egg yolks, I foolishly threw away the whites. WHAT WAS I THINKING? Hello?! There's a whole other meal in those whites.
I recently made ice cream that called for 6 egg yolks, and I am horrified at the thought that a couple years ago, those whites would've been tossed down the garbage disposal rather than having the opportunity to be a part of this delicious prosciutto, basil, and egg white omelet. Oh the injustice of it all!
I'm still making plenty of mistakes when it comes to cooking, but I'm glad I'm not making that one anymore!
