How to Prepare and Cook Beef Steak Mushrooms

More and more I've found I have to hunt mushrooms vicariously through other people during the growing season.

Thankfully I've built a pretty decent network around Minnesota and Wisconsin, and from there outliers stretching from China to Russia, Britain to Australia and beyond. Comparing notes on mushroom seasons around the world is an amazing by-product of this site I never expected.

Locally, My friend Alex, a mushroom hunting guide and I chat about what mushrooms are popping up or the occasional oddball shroom we can't find an ID for. Last year she sent me a picture of an interesting mushroom asking if I had an opinion on it.

It was a polypore, shelf-type growing from a tree, but not just any polypore. A chicken of the woods or a dryad's saddle are a dime a dozen compared to what we both knew was in the photo: a beefsteak mushroom, or Fistulina hepatica.

From my experience many mushroom hunters have never even heard of them. Beefsteak mushrooms, (also known as ox tongue mushrooms or fungus depending on your adjective preference) are a relatively rare polypore, the closest I'd come to eating them was reading about them in David Arora's Mushrooms Demystified, and Anthony Carluccio's The Complete Mushroom.

They're rare in their look, but also in flavor. The mushroom itself is red, resembling meat, and gives off a red juice when sliced, kind of like a very young chicken of the woods will leak a fragrant orange liquid when they're very young.

Habitat

Beefsteak mushrooms, like their cousins chicken and hen of the woods, are parasites, in my area, I really only see them on oaks, typically at the base of the tree, or on stumps.

I see them sporadically throughout the summer, and they seem to fruit heaviest in late summer, around august through September, at least from my experience.

Flavor

The flavor is where things are supposed to get interesting. They're a mushroom often eaten raw, supposedly with a sour flavor like sorrels (for the record it is only subtly sour, not at all as potent as any oxalis species I've consumed).

In a world where 99% of mushroom dishes are made with the same, bland cultivated mushroom cooked with cream or made into stroganoff, the beefsteak holds a place that's pretty unique.

I got excited. Alex said the mushroom was a little beaten up, but asked if I wanted to take a look at it, which I of course I did. She stopped by with a couple mushrooms and a paper bag filled with something wet, and heavy.

I remember holding the weight in my hands and peaking inside the bag, digesting feelings of excitement and uneasiness. What was in the bag resembled something from a murder scene: wet, bloody looking and viscous, it didn't exactly evoke inspiration.

I took the bag home to clean and inspect them the next morning. I wasn't the first to sample my beefsteak mushroom, slugs had already dined on the pores underneath.

Unlike when slugs and insects munch on hen of the woods though, or other similar polypores, the only portion of the mushroom they touched was the pores, the flesh or meaty part was completely untouched.

Surprising too was the complete lack of any white larvae, not a single one. Some mushrooms have natural resistance to the larvae, the beefsteak definitely has one if not the strongest resistance I've seen in a polypore.

I'm no scientist, but I might chalk it up to the sourness of the flesh, since acids like oxalis in plants (sorrel) can function as a defense mechanism against animals eating them.

Seasoned with chopped sorrel, salt and pepper, the mushrooms keep their crisp texture (they'll lose it after a while) this is a great place to start if you have some.

Cooking / Eating

Accounts of eating beefsteak mushrooms are not exactly common, but one similar thing I read is that people say they're sour like sorrel, with a texture like meat.

Well, from what I ate that's right, kind of. Sliced thin, the mushrooms are tender, with a little chewy bounce to them.

The flavor itself isn't anything remotely close to the powerful oxalic sour of sorrel or rhubarb. It does has a tartness, but the flavor to me came off diluted by the large amount of water the mushroom retains. In short it was slightly tart, tender, and watery.

The beefsteak was going to need some help. First I started by just putting some salt on it, which was better, then I started a few other experiments. They were seared in a hot pan, marinated, roasted in big pieces and sliced, then marinated, brined, dredged and fried, all kinds of stuff.

A lot of the resources I saw online said that the mushrooms will need long cooking to be tender, I didn't have that problem at all.

Sliced thin, as pictured below, I had no problem with them having a tough texture. Cooking was not my favorite, the mushrooms didn't taste like much, held a lot of water, and lost the crisp, tender texture that was so pleasing in the fresh mushroom.

I found I liked them raw, mixed with other ingredients and prepared simply, enjoying them the most when they tasted pure and un-manipulated. Beefsteaks are a fascinating wild mushroom, I just wish they tasted more sour!

A mushroom born to eat raw

After a few more years of cooking with these, I can definitely tell you that beefsteaks are best eaten raw-a novelty and anomaly among wild mushrooms. You don't need any fancy techniques or equipment for them to shine.

The first thing I made with them was a simple tomato salad. Over the years I've added a few others that are scattered throughout this post, seasoned with wood sorrel is one of the best, as is a simple tartare preparation where they take the place of diced meat.
