Original Receipt in 'The Closet Of Sir Kenelm Digby Knight, Opened' (Digby 1669)SMALLAGE GRUEL
In a Marble mortar beat great Oat-meal to meal (which requireth long beating) then boil it three or four hours in Spring water. To a possnet full of two or three quarts of water put about half a Porrenger full of Oat-meal, before it is beaten; for after beating it appeareth more. To this quantity put as much Smallage as you buy for a peny, which maketh it strong of the Herb, and very green. Chop the smallage exceeding small, and put it in a good half hour before you are to take your possnet from the fire. You are to season your Gruel with a little salt, at the due time; and you may put in a little Nutmeg and Mace to it. When you have taken it from the fire, put into it a good proportion of butter, which stir well, to incorporate with the Gruel, when it is melted.
