Mushroom Powder.
GET the largest and the thickest buttons you can, peel
them, and cut off the root end, but do not wash them.
Spread them separately on pewter dishes, and set them in
a slow oven to dry. Let the liquor dry up into the
mushrooms, as that will make the powder much stronger,
and let them continue in the oven till you find they will
powder. Then beat them in a marble mortar, and sift
them through a fine sieve, with a little chyan pepper and
pounded mace. Bottle it quite clear, and keep it in a
dry place.
