When I first wrote about my experience detoxifying and eating Amanita, some eight years ago now, I remember getting plenty of chippy comments from people in the mushroom community portraying me as a reckless, attention-seeking newb, which I expected, and understood. Muscaria is a polarizing mushroom, to say the least.
It’s widely known that if you eat Amanita muscaria raw, or even cooked from raw, you will get sick. It’s also widely known that the mushroom contains “other” compounds, that, when ingested after the right preparations, such as dehydrating, has been used as a narcotic, the sale of which is not at all uncommon under the table at local wicca shops, one of which I used to sell to occasionally when I was a broke line cook and sold out with pre-orders every year. Personally, I’ve never consumed it for anything other than culinary purposes.
What isn’t widely known, is that muscaria is also a traditional food in the form of fermented pickles in Japan (although it seems to be in a very small, localized region). It’s also documented in Russia. Culinary traditions involving fermentation of wild mushrooms are uncommon, and I know of only one other traditional mushroom fermentation in the salt pickling of milk caps and other mushrooms in Eastern Europe, which it seems, at least to me, is still prepared more or less regularly by their mushroom hunting descendants in the United States, if online mushroom groups are any barometer of use.
Bias in the literature
Every modern field guide I own makes no mention of traditional food practices involving muscaria. I’m not trying to say everyone should eat muscaria, or that it’s some huge revelation, but the examples of Western scientific bias ignoring food traditions is nothing new, Scandinavian murklor (Gyromitra) being another good example.
From the Falcon guide.On occasion, I’ve even seen guides branding the mushroom’s image in books with the same dreaded skull and crossbones applied to it’s lethal cousins in the Phalloideae, conveying the message that this mushroom is poisonous, and, if you make a false move, potentially deadly.
I knew Amanita muscaria could be rendered edible after boiling, but I had never heard of any specific culinary traditions featuring them until I read a paradigm-shifting experience posted by David Arora on one of the online mushroom groups I’m in. It was a fascinating, exciting read-one of many he’s shared online which are not exactly easy to locate. From an eater’s perspective, there’s a very big difference in trying to enjoy something that has been “rendered edible”, and sampling a culinary tradition documented first hand by a respected mycologist.
Before I forget to mention it, David wrote an academic paper on the subject with a lot of myth-busting, fascinating, and even off-putting tidbits (19th century testing on canines, etc) It’s well worth the read, even if you only glance at the abstract. The entire article can be viewed and downloaded here: A Study of Cultural Bias in Field Guide Determinations of Mushroom Edibility Using the Iconic Amanita Muscaria as an Example. I found it pretty interesting.
A Dwindling Japanese Food Tradition
In the post sharing his experience, David mentioned that over 20 years ago now, he traveled to the town of Ueda Japan to learn about the use of muscaria as an edible, and that they were typically boiled for 20-30 minutes and then brined to salt pickle them, and were, more or less common to harvest by people there. (as an aside, he also mentions that villagers were “horrified” to see him harvest porcini, which they absolutely did not harvest-the irony!)
In the last few years, David wrote that he’d decided to go back to the town to see if people were still carrying out the practice of detoxifying and preserving muscaria. Unfortunately, after the more recent trip, he wrote that fewer people seemed to be harvesting the mushrooms, and that the practice seemed to be in danger of dying out.
I find it a little depressing to imagine how many interesting food traditions that hold more value than just calories have been slowly extinguished and forgotten.
Of course, you know that after reading about something so obscure and fascinatingly funky I had to try fermented muscaria pickles. Well I did, and, they’re really not bad, I’ve actually been (gasp) enjoying them. All of my instincts made me presume that eating anything boiled within an inch of its life would taste like nothing afterward, but that’s not exactly true, and I think muscaria pickles are a pretty cool example.
I’ve fermented plenty of mushrooms, but isn’t something I reach for often. Fermented wild mushrooms can be good, in the right place, but those places are few and far between, as the finished product can be very strong tasting. And, depending on the particular species, the fermentation process is prone to making many mushrooms mushy, causing them to break down into pulpy, brown slimy goo, which, while not bad if you’re making a puree, isn’t exactly appetizing either.
Muscaria retains a good texture, and more flavor than you would expect. I can only presume that other edible amanitas, like velosa and mushrooms from the rubescens group, both of which I’ve also eaten (the former being excellent, the latter less-so) should produce a similar result.
Cooking, detoxifying, and fermenting
Finding the mushrooms is the difficult part, cooking is relatively easy, and will take about 30-45 minutes for the method I’ve used here. You cut the mushrooms into pieces, put them in a pot of water, boil, drain, immerse in salted water, and let sit on the counter like you would sauerkraut in brine. After a while, say 5-10 days, you put them in the fridge, where they’ll continue to age more slowly over the months.
In my first batch a few years ago, the first thing I noticed was that, gradually during the aging process, the mushrooms were no longer sitting in clear brine: they were immersed in a beige mushroom liquor. Like honey mushrooms, they gently thicken the liquid too over time, but it’s not mucilaginous like okra, it’s more silky and subtle.
My latest batch I’m eating as I write these were just warmed up in a bowl of miso soup, a preparation one of muscaria pickers shared with David Arora. It’s excellent, and at least for me, the best part is the texture. All the amanitas I’ve eaten have been similar in that the stems are a sort of chewy but tender mushroom bite, that, because of the hole in the middle, always reminds me of calamari. Muscaria is no different.
After fermenting and aging for a while, the mushrooms keep a delicious chew to them, and will sublty pick up aromas you add to the jar, although the basic traditional method seems to be nothing more than salt, boiled mushrooms and water.
I use a 3% weight of salt by volume here, so there will be a little less funk to the pickles, and the fermentation will be slower. If you want more tangy lacto-zip I’d use a 3-4% concentration of brine, or even 2% if you want them to sour quick (see my notes below if you’re unfamiliar with that.) Many of the common, edible milkcaps will be good like this too, as well as the hot and/or acrid ones, although the latter may need longer aging to soften the flavors.
It goes without saying that this should only be attempted by people who can confidently and correctly identify Amanita Muscaria, since lethal amanitas grow at the same time of year, often in close proximity. Please watch my video on detoxification of Amanita muscaria to familiarize yourself with the process beforehand if you would like to try them.
Japanese-Style Muscaria Pickles
- Vacuum sealer and bags
- Amanita Muscaria as fresh as possible
- Kosher salt as needed
- Splash of whey or juice from another ferment
- Filtered water
Detoxify the mushrooms
- Cut the mushrooms into pieces (see my video for reference) put in a pot of water at a ratio of 6 quarts of water to each 1 lb mushrooms, along with 2 tablespoons (26 grams) of kosher salt.
- Cover the pot and bring the mushrooms to a boil, still with the lid on, then set a timer for 15 minutes.
- After 15 minutes, remove the mushrooms rinse them vigorously and dry well, then put them in a glass jar or other non-reactive container placed on a scale tared to 0 in grams.
- Add water to cover the mushrooms by 1/2 inch, weighing the water and mushrooms in grams as you pour it in. Multiply the final grams by .03 or 3%, then add that many grams of salt to the jar. A pint jar is a good place to start, for that, you can use a tablespoon of kosher salt, or roughly 13 grams. Also remember that a pint is one pound, or 448 grams, and 448 x .03 = 13.44 grams of salt. (You can use anywhere from 2-5% salt here for reference).
- Add a dash of sauerkraut juice or fermented brine if you have some to speed up the process.
- Shake the jar, weigh the mushrooms down with a clean stone or clingfilm, screw on the lid, and leave in a dish to catch any liquid at room temperature for 5 days, and up to 10, or until they taste to your liking. The mushrooms should be covered with liquid the entire time.
- After that, refrigerate the mushrooms. The mushrooms will continue to age a bit in the fridge. If you want a stronger flavor, leave them out for another day or two, tasting them regularly.
- They'll last for a long time if always kept completely submerged in liquid, and will continue to develop as they age.
Fermenting without a vacuum bagYou can also pack the mushrooms into a jar with a weight on them as you would sauerkraut, if you want to do that, tare your fermentation container on a scale to 0, then add the mushrooms and water to cover. Multiply the combined weight in grams of the mushrooms and water by .03, then add that amount of salt in grams, stir to dissolve, and put a weight on the mushrooms to keep them under the brine, then ferment per usual.
