3In a large pot, combine the soaked Black beans, 75 grams of the White onion (roughly chopped), 10 grams of the Garlic cloves (peeled), and the toasted 5 grams of Avocado leaves. Add 1500 grams of fresh Water, ensuring the Black beans are fully submerged. Bring to a boil, then reduce heat to low, cover, and simmer for 1.5 to 2 hours, or until the Black beans are tender.
