Question about this recipe

They mean dried raw ones, because the canned kind are already cooked. But if you want to use canned ones instead, just skip the soaking and boiling them and throw them in the blender straight from the can. I would drain them and use a bit of water if you need some liquid where it calls for the cooking liquid.

And one cup dried would be more at the end, so I would use a whole can, not a measured cup, because they expand when soaked and cooked.
