Anthocyanins are pigments that, depending on their pH, may appear red, purple, blue or black. Food plants rich in anthocyanins include the blueberry, raspberry, black rice, and black soybean, among many others that are red, blue, purple, or black. [wikipedia]
Wikipedia offers a list of food sources with high anthocyanin levels. I put them in descending order below. You might choose to use them to color your cocktails.
- Purple corn leaves
- Purple corn [buy]
- Dried red cabbage
- Norton Grape
- Black Raspberry
- Concord grape
In my next post, I have links to many different natural food/drink colorings.
