Have you ever cooked beans from dried? Black beans will take a couple hours to cook or shorter if you use a pressure cooker. Some people cook them overnight in a crockpot. When cooking beans, you'll need about 2 cups of water per cup of dried, soaked beans. I'd google for information, I kind of just estimate the amount of water for cooking beans.
If you are just trying to follow the recipe, it isn't a lot of water, maybe 1/4th cup per cup of cooked beans but I'd also add water as you see fit with the recipe.
You can't out-exercise poor eating habits.
