Put the medium pot on the stove and turn the heat on high
Add the water
6 cups water
Put the colander in the sink and put the beans in it
12 oz dried black beans
Rinse the beans and remove any not-beans you may find, such as small rocks or debris
Transfer the beans to the pot
Add the salt, oil, lime juice, powders, and any other seasonings you want to the pot
1 tsp salt, 1 tsp garlic powder, 1 tsp cayenne/chili powder, 1 tsp olive oil
Let the water come to a boil
Reduce the heat to about medium, such that the water is gently simmering
Cook the beans for 1 hour
Carefully (because they'll be hot) eat a bean or two to see if they're tender enough. If not, check again every 10 minutes, until they are. Add more water if need be, to keep the beans swimming in it. Turn the heat on high again, to boil away the water and thicken the bean sauce
Once most of the water has boiled, turn the stove off
Add the lime juice
1 tbsp lime juice
Serve the beans
