MUSHROOM POWDER (a valuable addition to Sauces and Gravies, when fresh Mushrooms are not obtainable).
477. INGREDIENTS.—1/2 peck of large mushrooms, 2 onions, 12 cloves, 1/4 oz. of pounded mace, 2 teaspoonfuls of white pepper.
Mode.—Peel the mushrooms, wipe them perfectly free from grit and dirt, remove the black fur, and reject all those that are at all worm-eaten; put them into a stewpan with the above ingredients, but without water; shake them over a clear fire, till all the liquor is dried up, and be careful not to let them burn; arrange them on tins, and dry them in a slow oven; pound them to a fine powder, which put into small dry bottles; cork well, seal the corks, and keep it in a dry place. In using this powder, add it to the gravy just before serving, when it will merely require one boil-up. The flavour imparted by this means to the gravy, ought to be exceedingly good.
Seasonable.—This should be made in September, or at the beginning of October.
Note.—If the bottles in which it is stored away are not perfectly dry, as, also the mushroom powder, it will keep good but a very short time.
