Smoothie bowls and açaí bowls are similar in that they both use fruit as a base, but they differ in origin and texture. Açaí bowls originated in Brazil and are made with açaí berries, which have a sorbet-like consistency. Smoothie bowls, on the other hand, are made with pureed fruit mixtures and have a thicker, more spoonable consistency. They originated from the smoothie bar trend in the early 2000s.
