Hi Bill, thanks for your comment and your question. Growing up, we always had a blender, but my great-grandparents did not have one until later in their lives. The device that they would use for blending ingredients for horchata and other recipes is called a Metate. Here is a link. so you can see what it looks like. It definitely took more time, but it seemed to work! I still remember seeing my great-grandparents use this even after we had blenders at home!
