There is a story which explains the name given to this drink. The story says a villager led the king of the Crown of Aragon some horchata. The king dazzled the taste and asked what it meant. The girl replied that it was groundnut milk (llet of Xufa in Català), the name was known drink. The king said, “Aixó no es llet, Aixó es OR, XATA!” that means: “This is not milk, this is gold, honey!”. It caused a pun on “OR” and “XATA” giving the supposed origin to the word “orxata” way to write in that language.
You have to teasted!
