To begin, grab a medium-sized pot and add about 4 cups of water for every 1 cup of garbanzo beans you're using. Now, I know what you're thinking - "do I really need to use that much water?" And the answer is, yes, you do, because those beans need room to expand and get all cozy in their new surroundings.
Next, add a pinch of salt - don't be shy, now - and bring that water to a boil. Once it's rolling, reduce the heat to a simmer and let those beans cook for about 45-50 minutes, or until they're tender and creamy.
