I made myself a smoothie just now with frozen wild blueberries, low fat yogurt, pomegranate/blueberry juice, honey matcha powder, and golden flax meal.
It's a little weird, kind of a scary not-all-the-way purple color, with a very plant-y taste (from the matcha) and a little bit of texture from the flax meal.
I kept trying to think where I had seen this color and tasted this flavor before, and suddenly it hit me: this stuff looks and tastes exactly like sweetened acai pulp. Well, okay, not exactly: it's less oily. But when you consider that the health benefits are very similar (loads of antioxidants plus some omega fatty acids), it becomes even more eerie. Perhaps I've just blown the lid off of this conspiracy: there is no such thing as acai, there is is only a factory in Brazil where they mix blueberries and matcha and flax and flax oil and pomegranate juice. They gave it an exotic name to con the unsuspecting American public into buying products they already knew about, but hadn't thought of combining!
The other and perhaps weirder possibility is that this particular combination of nutrition has a distinct taste.
Or maybe it's just that I've heard a fair number of people compare the taste of acai to blueberries, and the first time I tasted I remarked how much it tasted like "eating tea". But who likes boring answers like that?
I really like acai, actually. It's fairly nasty in unsweetened pulp form, but once you add just a little sugar it's really good. If you ever manage to find this product, I HIGHLY recommend it. It's crazy delicious. I like it because it's non-dairy, and full of health, but still super fatty (NOM NOM NOM) and sweet and tasty. It's like... like sorbet you would eat for breakfast. It's extremely filling, and in a good way, not in an "I just ate lots of ice cream and am now sick" way.
