Popeyes Red Beans

3 (15 1/2-ounce) cans red beans, divided
1/2 to 3/4 pound smoked ham hock
1 1/4 cups water
1/2 teaspoon onion powder
1/2 teaspoon garlic salt
1/4 teaspoon crushed red pepper
1/2 teaspoon salt, or to taste
1/4 teaspoon freshly ground pepper
1/4 cup plus 1 tablespoon lard
4 to 5 cups cooked long grain rice, drained

Pour 2 cans of beans with their liquid into a 2-quart pan. Add the smoked ham hock and water. Bring the pan to a simmer on medium heat for an hour, until the meat starts to loosen from the bone. Remove from the heat and cool until the ham hock is cool enough so the meat can be removed from the bone. Place the meat, beans, and liquid in a food processor. To the mixture add the onion powder, garlic salt, crushed red pepper, salt, pepper, and lard. Process for only 4 seconds. The beans should be chopped and have a soupy, liquid consistency. Now drain the liquid from the remaining can of beans and add the beans to the food processor. Process just for a second or two—you want these beans to remain almost whole. Pour the bean mixture back into the pan and cook slowly on low heat, stirring often, until ready to serve. Serve the beans over the cooked rice.
