*If you forget to soak your beans, cover the beans with water and bring to a boil. Boil for 1 minute. Turn off the heat, cover and let sit for at least 1 hour. Drain and rinse. Proceed with the recipe.
*If you don't want the spicy note that Serrano pepper brings to the party, use ½ of a green pepper instead. This will give good pepper flavor without being spicy.
*In our house we are old school (and southern) so we save our bacon fat (grease) from the morning. If you don't have bacon fat on hand or the thought of bacon fat weirds you out, add a couple strips of raw bacon. If you prefer, you can totally leave out the bacon/fat. Adding pork to beans gives the beans an umami depth of flavor that you can't get from anything else. The beans will taste good without the bacon... just not as good.
