My favorite is "Any Whey" unflavored protien powder. It was made to be used when cooking or eating in regular non-solid foods (like yogurt, pudding). It has a sweet smell, kinda like cotton candy, but it does not have a taste. I put it in my yogurt or cottage cheese at breakfast, then put in any foods I cook for dinner, like meatloafs or gravies. You can find it at GNC or Bariatriceating dot com.
If you are looking for a flavored powder (choc or vanilla), I agree that Unjury is the best.
