Unflavored unjury
Sucks huh? None of the unflavored protein powders I have ever encountered are flavorless. They just don't add any flavorings. Tossed my first scoop into some cottage cheese.
You have to put it in things that have a stronger taste. I was able to use it in soups, just make sure you temper it before you add it or it clumps if your soup is too hot. Same with coffee which wasn't too awful. I would mix in tiny amounts into my other protein shakes. Once I tossed some into a turkey meatloaf just to use some of the stuff.
In the end I got rid of close to half a tub.
Edited to add: have you checked out bariatricfoodie? Just google it and her blog should come up. She does have a lot of protein shake receipes (and food recipes for post-op) and she is bound to have one that will help you hide the taste.
