Pickled Mushrooms by THFool Dagonell Jongleur

Original Text:
Champignons are best, that grow upon gravelly dry rising Grounds. Gather them of the 
last nights growth; and to preserve them white, it is well to cast them into a pitcher 
of fair-water, as you gather them: But that is not absolutely necessary, if you will 
go about dressing them as soon as you come home. Cut the great ones into halves or 
quarters, seeing carefully there be no worms in them; and peel off their upper skin on 
the tops: the little ones, peel whole. As you peel them, throw them into a bason of 
fair-water, which preserves them white.

Then put them into a pipkin or possnet of Copper (no Iron) and put a very little water 
to them, and a large proportion of Salt. If you have a pottle of Mushrooms, you may 
put to them ten or twelve spoonfuls of water, and two or three of Salt. Boil them with 
pretty quick-fire, and scum them well all the while, taking away a great deal of 
foulness, that will rise. They will shrink into a very little room.

When they are sufficiently parboiled to be tender, and well cleansed of their scum, 
(which will be in about a quarter of an hour,) take them out, and put them into a 
Colander, that all the moisture may drain from them. In the mean time make your pickle 
thus: Take a quart of pure sharp white Wine Vinegar (elder-Vinegar is best) put two or 
three spoonfuls of whole Pepper to it, twenty or thirty Cloves, one Nutmeg quartered, 
two or three flakes of Mace, three Bay-leaves; (some like Limon-Thyme and Rose-mary; 
but then it must be a very little of each) boil all these together, till the Vinegar 
be well impregnated with the Ingredients, which will be in about half an hour. Then 
take it from the fire, and let it cool.

When the pickle is quite cold, and the Mushrooms also quite cold, and drained from all 
moisture: put them into the Liquor (with all the Ingredients in it) which you must be 
sure, be enough to cover them. In ten or twelve days, they will have taken into them 
the full taste of the pickle, and will keep very good half a year. If you have much 
supernatant Liquor, you may parboil more Mushrooms next day, and put them to the first.
If you have not gathered at once enough for a dressing, you may keep them all night 
in water to preserve them white, and gather more the next day, to joyn to them."

Champignon is the medieval term for white button mushrooms.  'Of last night's growth' 
means ones that weren't there the previous night.  I chickened out and got packages 
from the grocery store. :) Pipkins and Possnets are small cooking pans.  Pottle is an 
archaic unit of measure equal to a half gallon.  Twenty or thirty cloves???  Um, no.  
Just no.  By liquor, he means the pickling liquid, not alcohol. Supernatant liquor is 
liquid over a solid residue.  I didn't realize the term was that old!  
One pottle of mushrooms = 1/2 gallon = 1892.7 grams
One package of mushrooms = 12 oz = 340 grams = ~20% of a pottle

Original Text:
Take your Buttons, clean ym with a spunge & put ym in cold water as you clean ym, 
then put ym dry in a stewpan & shake a handfull of salt over ym, yn stew ym in their 
own liquor till they are a little tender; then strain ym from ye liquor & put ym upon 
a cloath to dry till they are quite cold. Make your pickle before you do your 
Mushrooms, yt it may be quite cold before you put ym in. The pickle must be made with 
White-Wine, White-Pepper, quarter’d Nutmeg, a Blade of Mace, & a Race of ginger."

Take your Buttons, clean them with a sponge and put them in cold water as you clean 
them, then put them dry in a stewpan and shake a handful of salt over them, then stew 
them in their own liquor till they are a little tender; then strain them from the 
liquor and put them upon a cloth to dry until they are quite cold. Make your pickle 
before you do your mushrooms, so it may be quite cold before you put them in. The 
pickle must be made with white wine, white pepper, quartered nutmeg, a blade of mace, 
and a race of ginger.

Again, the liquor is not alcohol, but the pickling liquid.  Nutmeg and mace both come 
from the same plant, Myrstica fragrans.  Nutmeg is the seed, mace is the lace-like 
peel.  A blade of mace is about 1/6 of the entire peel, call it about a 1/2 teaspoon.
A race of ginger is one piece of root.  

3/4 cup water (12 tablespoons)
2 tablespoons salt
36 oz. fresh mushrooms (3 pkgs)
1 quart white vinegar
2 teaspoons white pepper
3 cloves (not 30!)
1 whole nutmeg, broken (place in baggie, wrap in towel, hit with hammer)
1/2 teaspoon powdered mace
3 bay leaves
1 small ginger root, peeled and sliced

In a small saucepan, combine water, salt and peeled mushrooms.  Simmer for 15 to 20 
minutes.  It looks like there's not enough liquid.  You just need enough to keep the 
mushrooms from scorching until they start to tenderize.  They will give up half their 
weight as liquid.  When the mushrooms are tender, strain them in a colander over a 
second saucepan.  Don't throw away the liquid, it makes a great mushroom broth for 
homemade soup!  If you use commercial mushrooms, there won't be any scum to deal with.
In a third saucepan, combine vinegar, pepper, cloves, nutmeg, mace, bay leaves, and 
ginger root.  Bring to a boil.  Let everything cool.  Place the mushrooms in a clean 
jar, pour the pickling liquid over them, and seal.  Let marinate for two weeks.
