NOTE: Depending on how old your beans are they may cook within an 1 h and 1/2 but they may take up two 2 hours. Keep on checking toward the last half hour to make sure it has reached a good consistency where the beans are soft and most importantly the broth isn't very liquidy anymore but rather creamy and slightly thick (it will thicken more later on or the next day). Most of the liquid will be reduced to a creamy broth that is leveled with the beans (as per photos).
