Rice protein tastes ok (a bit like mushrooms), but casein and of collagen protein are the only ones that are actually tasty by themselves, just diluted with water.
I really really wanted to like pea protein, but calling it wet cardboard is really doing a disservice to the wet cardboard cuisine.
I fear with this kind of campaign behind it it will now find its way to the majority of shakes and meals and the taste will be just everywhere.
