"SORREL VERJUICE. Grind the sorrel very fine without the twigs, and soak in old, white verjuice, and do not strain the sorrel, but let it be finely ground; or thus: grind parsley and sorrel or wheat-leaves. Item vine buds, that is those that are young and tender, without any sticks."

"Here is how to make green sauce: take ginger, cinnamon, pepper, nutmeg, cloves, parsley, and sage. First grind the spices, then the herbs, and add a third of the sage and parsley, and, if you wish, three or two cloves of garlic. Moisten with vinegar or verjuice. Note that to every sauce and condiment salt is added, and crumb of bread to thicken it."
