In a 2 quart pot, sauté the pancetta (or bacon) on low to medium heat to crisp up and render the fat, 3-5 minutes.
Using a slotted spoon, remove the pancetta to a small bowl, leaving the renderings in the pot.
Sauté the onion and jalapeno on low heat until almost soft, 5-7 minutes.
Add the garlic and sauté 2-3 minutes more.
Add the beans and pancetta and stir to combine.
Add the brown sugar, oregano, liquid smoke, Worcestershire sauce, molasses, and crushed red chili flakes. Stir to combine.
Taste and adjust salt and pepper.
Simmer on low heat, covered, for 1-2 hours. (optional: do in a slow cooker or a Dutch oven in a low oven)
Set the lid ajar and simmer another hour.
