Step 1

Put mayocoba beans into a large container with enough cool water to cover by several inches. Let beans soak 8 hours to overnight.

Step 2

Drain mayocoba beans and rinse thoroughly; put into a large stockpot. Pour enough water into the pot to cover beans by a few inches; bring to a boil, reduce heat to medium-low and place a cover on the pot, and cook at a simmer until beans are soft in the center, about 90 minutes.

Step 3

While the beans simmer, heat oil in a large skillet over medium heat. Cook and stir onion in hot oil until tender, about 5 minutes; add tomatoes and serrano pepper and simmer until the tomatoes have softened slightly, about 5 minutes. Reduce heat to medium-low and continue cooking until the liquid begins to thicken, about 10 minutes more. Remove from heat.

Step 4

Cook and stir bacon in a large, deep skillet over medium-high heat until very crispy, about 10 minutes; remove bacon from skillet with a slotted spoon and drain on a plate lined with paper towel.

Step 5

Cook ham cubes in the bacon fat in the skillet until browned, about 5 minutes; remove with slotted spoon to the plate with the bacon to drain.

Step 6

Once the beans have cooked, stir the tomato mixture, bacon, ham, beer, jalapeno peppers, cilantro, and chicken bouillon granules into the beans; season with sea salt. Bring the mixture to a simmer and cook until the beans are completely softened, about 30 minutes.
