Clean the beans

• Spread the beans on a clean counter and sort through them quickly.
• Remove any rocks, floating beans, broken half pieces and very dark beans that don't look right.
• Rinse the beans in a colander.

Start cooking

• Put the beans in the pot and cover generously with water.
• Add the onion and garlic cloves.
• Bring to a boil, then lower the heat, cover with the lid and simmer.

Check and add flavor

• Check the beans after an hour of simmering.
• Stir in the jalapeño juice for extra flavor.
• Add more water to keep a good amount of broth.

Season and finish

• Salt the beans generously.
• Simmer uncovered so everything combines, until the beans are completely tender.
