Source [Le Menagier de Paris (Janet Hinson, trans.)]: HIPPOCRAS. To make powdered hippocras, take a quarter-ounce of very fine cinnamon, hand-picked by tasting it, an ounce of very fine meche ginger and an ounce of grains of paradise, a sixth of an ounce of nutmeg and galingale together, and pound it all together. And when you want to make hippocras, take a good half-ounce or more of this powder and two quarter-ounces of sugar, and mix them together, and a quart of wine as measured in Paris. And note that the powder and the sugar mixed together make "duke's powder".
