I bought this stuff thinking I'd just mix it with crystal light to get in more Protein but it's got a funny taste/smell.

How can you use this stuff without having that weird taste?

Could you put in soups or make your own smoothie with some fruit to cut the taste?

I have it. I don't think it has a taste of smell. I put it in soup. Applesauce (unsweetened). Crystal light. Oatmeal. Sugar free pudding. Broth. Anything liquid I add some in. Even if it's not a full scoop I always add some.

It's a matter of taste. I like it and add it to pretty much everything. Soups, tea, my yogurt, etc.... If you don't like Ispoure Genepro and Syntrax Nectar also make and unflavored version. Remember unflavored doesn't mean flavorless, it just means there's no added flavorings or sugars. Adding stronger flavors to it helps. I add a dash of hot sauce to my soups or a bit of lemon to my tea.

Yeah, soups and smoothies I can see would be good uses. On the package it says "add to any food" but other than liquid food, what ways can it be used?

I understand unflavored does not mean flavorless, but it shouldn't have an odd, unpleasant flavor either.

I bought the liquid Protein drinks, also by Isopure, and they don't have that aftertaste, but they are pricey, comes out to about $2.50 each on amazon (for a pack of 24).

Thanks for your comments.

I've added it to egg salad, scrambled eggs, and yogurt. With eggs I use less, no more than half a scoop, sometimes only a quarter scoop. I've also added it to spaghetti sauce.
