Exactly! When a (vegan) person I met discovered horchata ('de chufa', there are other drinks called 'horchata') they commented on using it as their new plant-based milk and I said 'not so fast! This is basically sugar!' but then I read the nutritional info on their oat (I think) 'milk' and was like 'never mind.. this is the same'.
On a side note I didn't know tiger nut is English for 'chufa' which is the (nick) name of my dog. I'm gonna start calling her Tiger nut, it sure suits her!
