Two that come to mind are:
Pickle Juice - yes I drink it from the jar. If this disgusts you perhaps you can try these alternatives to throwing it out because it is packed with flavor. Mmmmmmm.....pickle juice.
Milk Skin - I will purposefully overcook my hot chocolate milk to get a nice thick layer of milk skin. It tastes like Cream O' Wheat. Also, my mom's vanilla pudding has the best skin ever.
Kind of a short post today but I don't really have much else to say about these two things except that I love them. So there you go.
