Procedures

1. 1

2. 2

   Add the beans and 8 cups of water (or, again, whatever your manufacturer says). Stir. Cover and seal the pot and cook for 35 minutes. Turn off and allow the pressure to release naturally. Check a bean. It should be completely tender. If not, bring back to a simmer and cook a little longer.

3. 3

   Carefully remove the cover. Drain the liquid from the beans, reserving a couple cups of it and return the beans to the pot. Add 1 teaspoon of salt to the beans and 1 cup of the reserved liquid. Using an immersion blender, puree them thoroughly. If they need more liquid, add 1/4 cup at a time until you reach the desired texture. Taste and adjust the salt, you might need another 1/2 teaspoon or so.

4. 4

   Serve them forth as part of a Mexican meal. Garnish with a bit of queso anejo or queso fresco. You can freeze any leftovers.
