Draining beans can be a good idea, especially if you're using canned beans, which are often packed in a salty liquid that can make your chili taste like a sodium bomb went off in your mouth. By draining and rinsing the beans, you can reduce the sodium content of your chili and make it taste fresher and more balanced. Plus, it's just nice to get rid of all that excess liquid, you know, for texture purposes.
But, on the other hand, not draining beans can be a good idea too, especially if you're looking for a thicker, heartier chili. The liquid from the beans can help to thicken the chili and add more flavor to the pot. And let's be real, who doesn't love a good, thick chili that's just begging to be topped with a mountain of cheese and onis?
