Those who live in the Country, or go to Sea, have frequent occasion to use Mustard, when there is no opportunity of getting it without extraordinary Trouble. It is a Sauce seldom thought on till the Minute we want it; and then, according to the old Way of making it, if we are lucky enough to have Mustard-Seed in the House, we must spend an Hour in the Ceremony of grinding it in a wooden Bowl, and an Iron Cannon-Bullet, according to the old Custom; or, if we have Mustard by us, ready made, if it has stood a Week, it is then of no value, if it is in small quantity. But to obviate this Difficulty, the Invention of grinding Mustard-Seed in a Mill, and thereby reducing of it to Flour, to be made fit for the Table in an instant, has been very well received: for by that Contrivance we have it always fresh, and full of brisk Spirits, and may only make just what we want without any spoil, as long as we keep a Stock of this Flour by us. There are two Sorts of Mustard: _viz._ The white Sort, which is a large Grain, and not so strong; and the black Sort, which is a small Grain. That which I account the best, is from the wild Mustard, commonly found growing in _Essex_, which sells the best in the Markets. But from whatever Place we have it, regard should be chiefly had to its being free from Mustiness, which happens from the gathering the Seed wet, or in the Dew, and laying it close together before it is thresh'd. When this Seed is dry and sweet, grind it in a Mill, such as a Coffee-Mill; but the Mill must be fresh, and free from any Flavour or Taint: it should not indeed be used with any other thing. When you have ground a sufficient Quantity, pass it through a pretty open Sieve, and the next day put it into Vials with open Mouths, pressing it down close; stop them well, and keep it for use. When you want good Mustard for the Table, take a spoonful or two of this Flour, and as much boiling Liquor from the Pot, where Beef or Pork is boiled, as will make it of the Consistence you desire, stirring it well till it is mixt for your Purpose; or for want of such Liquor, boil a little Salt and Water together, and mix your Mustard-Flour with that; but in either of these Ways you must observe, that while your Mustard is warm, it will last better. Some who do not love their Mustard overstrong, put equal Quantities of the white and black Mustard-Seed into the Mill, and then the Flour will not be so poignant to the Palate, and will have a brighter Look. If your Mill be set very sharp, the Flour will be so fine, that it need hardly be sifted. To keep _Anchovys_ good for a long time. From Mrs. _M. N._
