Step 1

Heat a large pot. Swirl in the oil. Add the onion, celery, bell pepper, and garlic and saute until soft and lightly caramelized, 11 to 12 minutes.

Step 2

Drain and discard the soaking liquid from the beans and add the beans to the pot. Pour in the fresh water and stir. Bring to a boil, reduce the heat, and simmer uncovered for 1 hour. Skim off any foam as it rises to the surface.

Step 3

Add the ham bone, Tabasco sauce, salt, thyme, and bay leaf. Continue to cook until the beans are soft and tender, 30 to 60 minutes more. (The time will vary depending on the age of the beans, so taste frequently.) Using the back of a spoon or spatula, crush some of the beans against the side of the pan to create a slightly creamy consistency.
