Mushroom Powder

Method

When the mushrooms have been prepared with great nicety, and dried, as in the foregoing receipt, pound them to a very fine powder; sift it, and put it immediately into small and perfectly dry bottles; cork and seal them without delay, for if the powder be long exposed to the air, so as to imbibe any humidity, or if it be not well secured from it in the bottles, it will be likely to become putrid: much of that which is purchased, even at the best Italian warehouses, is found to be so, and, as it is sold at a very high price, it is a great economy, as well as a surer plan, to have it carefully prepared at home. It is an exceedingly useful store, and an excellent addition to many dishes and sauces. To insure its being good, the mushrooms should be gathered in dry weather, and if any addition of spices be made to the powder (some persons mix with it a seasoning of mace and cayenne), they should be put into the oven for a while before they are used: but even these precautions will not he sufficient, unless the powder be stored in a very dry place after it is bottled. a teaspoonful of it, with a quarter of a pint of strong veal gravy, as much cream, and a small dessertspoonful of flour, will make a good béchamel or white sauce.
