Brined beans

 Soaking beans in a solution of salt and baking soda yields creamy, cooked beans in less time.

 There’s a whole wide world of beans out there, from broad and flat fava beans to small,  curvaceous pintos. The variation in beans is obvious in both their many shapes and in their many colors, but it's also apparent in the fact that different kinds of beans require different cooking times and preparation methods. Some beans cook up more quickly, becoming tender and creamy in a relatively short amount of time, whereas others take ages and ages to cook and may benefit from a soak in water beforehand.
