another method to cover the top but i find that using your hand works best. as the liquid already in the can is drained and you replace it with water, you create a thinner liquid that still has some of the “bean juice” flavor. i rinse then this way about 2-3 times, filling the can with as much water as i can until the beans start to overflow. finally, i empty the water that is in the can but leave about an inch or two of water still in the can so that when i add them to a pan, there is some liquid available that is now a mixture
