I have to just mention this here

I just made the best beans I ever tasted and the texture is perfect too. I pureed them for refritos and they need nothing added to be heaven.

Also almost the simplest ever too. All I did: overnight soak with salt, cooked at a low simmer for several hours, run through the blender with the cooking water and a couple tablespoons more, blend blend blend until it is as smooth as sour cream.

Small red beans.

I'm in paroxysms of yum.
