Black Beans or Black Turtle Beans ~ known generally to the cooking world, this bean makes a wonderful food dye. Not necessarily very colourfast, it matures into a beautiful ceramic colour - silver grey with a touch of blue. Because you are only using the soaking water, you can use the beans for cooking afterwards, making it a very 'no waste' food dye.
