1 pound beans (I used pinto here, but you could use red or black)
1/2 tablespoon salt
Recipe
Preheat the oven to 250.
Dump the beans into a large dutch oven or pot with tight fitting lid. Pick out any broken pieces. Add the salt. Top with enough water to cover the beans by an inch and a half. Bring pot to a boil.
Then cover the pot, and set in the oven. Cook for 75 minutes.
About 45 minutes in, check on the beans. If they look too dry add some boiling water to the pot. Mine did not need any.
After 75 minutes they should be done.
