Black garlic is not new to the market, but it's also not that easy to find. While I've seen some Asian grocers carry black garlic based sauces, black garlic itself doesn't seem to be readily accessible. Either way, I'd recommend checking out South East Asia Food Group if you're in the NYC area, asking your local Asian grocers, Amazon, or ordering a black garlic sauce to work with. It's totally worth it. To learn more about black garlic, check out Japanese company, Momiki. They export several of their products to the U.S. and it's where I get all my black garlic products from.
