Mushroom Ketchup No 3 Recipe
Pick the mushrooms clean, but by no means wash them; put them into an
earthen pipkin with salt, cover them close with a coarse paste, and put
them in the oven for seven hours or thereabout. Squeeze them a little,
and pour off the liquor, which must be put upon fresh mushrooms, and
bake these as long as the first. Then pour off the liquor, after
pressing, and boil it well with salt sufficient to keep. Boil it half
away till it appears clammy. When cold, bottle it up.
