In a large stockpot over medium heat on the stove, heat the oil. Add the onion, garlic, and jalapeño and cook until the onion is tender, about 5 minutes, stirring occasionally. Add the oregano, cumin seed, salt, and pepper and cook until fragrant, about 30 seconds, stirring constantly. Pour in the lager and add the bay leaf. Place the short ribs in the braising liquid, meaty side down, and add just enough water to cover them. Bring to a boil over high heat and then reduce the heat to low. Cover and simmer until the ribs are barely tender when pierced with the tip of a knife, about 1½ hours. Transfer the ribs to a sheet pan to cool. Remove and discard any bones that may have fallen off the ribs in the liquid; reserve the liquid. Cover and refrigerate the cooled ribs until chilled, about 2 hours.
