Mushroom Ketchup.
Take a parcel of mushrooms either natural or forced, the latter will prove the best, and cut off part of the stalk towards the root. Wash the mushrooms clean,[307] drain them, then bruise them a little in a marble mortar, put them into an earthen vessel with a middling quantity of salt, let them remain for four days, and then strain them through a tamis cloth. When the sediment is settled pour the liquor into a stewpan, and to every pint of juice add half a gill of red port, a little whole allspice, cloves, mace, and pepper. Boil them together twenty minutes, then skim and strain the ketchup, and when cold put it into small bottles and cork them close.
