Calling canned beans "a shortcut" is funny because most people can't even tell the difference in a blind taste test. Grandma's pot tasted better for a dozen reasons that have nothing to do with the bean itself, like way more salt, fat, and hours of simmering with a ham hock or bacon. Canned beans dumped into that same pot with the same stuff would taste almost the same, I'd bet money on it. Plus dry beans take forever, need soaking, and you have to plan a day ahead, which is a huge pain when you just want dinner. Canned beans are cheap, fast, and honestly pretty good if you rinse them and doctor them up a bit. The real magic was grandma's recipe, not the bean, and you're giving dried beans credit they didn't earn.
