Collard liquor, also known as pot liquor, sometimes spelled potlikker or pot likker is the liquid that is left behind after boiling greens (collard greens, mustard greens, turnip greens); it is sometimes seasoned with salt, smoked pork or smoked turkey. Pot liquor contains essential vitamins and minerals including iron and vitamin C. Especially important is that it contains a lot of vitamin K, which aids in blood clotting.
Former Senator and Governor of GeorgiaZell Miller wrote a defense of the traditional spelling 'potlikker' to the New York Times.
