After spending the summer learning some of the ins and outs of foraging, I was delighted to find a new cookbook dedicated to my all-time favorite foraged food: earthy, meaty mushrooms. Written by Becky Selengut, a Seattle chef, author, teacher, humorist and forager, “Shroom: Mind-bendingly Good Recipes for Cultivated and Wild Mushrooms” provides a detailed yet fun-filled look at 15 wild and cultivated mushrooms and how to select, store, clean, prepare and pair each.
A native of New Jersey, Selengut’s infatuation with fungi began in childhood, when she tinkered with cooking white button mushrooms at home and indulged in stuffed mushrooms with her family at the Basque restaurant Jai Alai in Dover, N.J.
“It wasn’t great porcini hunting that day, but he told me how to spot them, just coming up through the duff, and, well, I had beginner’s luck and kicked at the dirt and I found the only ones we saw that day,” Selengut said.
Thrill to unearthing treasure
As Selengut can attest, there is a unique thrill to unearthing one of nature’s edible treasures. An even greater rush occurs when you slip into the kitchen to cook your wild, hand-plucked bounty. But what if you’re a newcomer to mushrooms and unsure how to properly prepare this delicacy?
Realizing that bad recipes and poor cooking techniques have thwarted many prospective mycology fans, Selengut leads “Shroom” readers through basic recipes, storage advice and cleaning tips for mushrooms. She also provides links to handy how-to videos she has filmed. Thanks to her thoroughness and approachability, even the greenest cook can step into the kitchen with confidence and create a scrumptious mushroom dish.
Selengut arranges each chapter of “Shroom” from the simplest to the most difficult recipes. Her first two offerings speak to novice or time-pressed cooks. Perfect for those craving easy dinners ready in 45 minutes or less, they include such flavorful specialties as oyster mushroom ragout and Sweet Potato Soup With Lime Leaves, Beach Mushrooms, Basil and Peanuts (see recipe below).
Meals requiring multiple techniques and exotic ingredients are classified as intermediate recipes. With these, readers learn how to whip up Roasted Portobello Tacos With Cacao-Chili Sauce and Cabbage and Lime Slaw; cheese and fig-stuffed morels; and pickled chanterelles. In every chapter, Selengut provides two intermediate dishes.
The remaining fare in “Shroom” speaks to adventurous and skilled home cooks as well as professional chefs. Sauces, meats and sides factor into these preparations. Savory entrees such as Hanger Steak With Porcini, Blue Cheese Butter and Truffled Sweet Potato Frites and Black Trumpet Mushroom Tarts with Camembert, Leeks and Port-Soaked Cherries are part of this advanced category. Although more challenging and time consuming than earlier recipes, these courses remain accessible and delicious.
“My favorite way to prepare mushrooms flavor-wise would be over a live fire — cast-iron skillet on the grill, lid down to capture the wood smoke — or in a wood-burning oven. My favorite way to prepare mushrooms efficiency-wise is to spread them out on a sheet pan and roast them in a hot oven, at least 400 degrees, with a little oil, salt and pepper,” Selengut said.
Countless dishes around the world
In “Shroom” Selengut points out that whether they star or play a supporting role, mushrooms appear in countless dishes around the world. This global presence flavors much of her vibrant book. Vietnamese báhn xèo, Indian tandoori, Italian acquacotta and Japanese chawanmushi all find their way into the cookbook.
So, too, do a variety of wild and farmed mushrooms. Along with the tried and true Portobello, cremini and button, the petite beech, spiky lion’s mane and reddish-orange lobster receive their due.
Among all the uncultivated mushrooms found in the Pacific Northwest and in her book, Selengut singles out the black trumpet mushroom as her favorite. “It’s naturally smoky, earthy and just a little fruity — buckets of flavor and umami. It smells like the sexiest forest imaginable. Favorite cultivated is a tie between maitake and shiitake, both extremely flavorful despite being farmed and lots of promising research about health properties, specifically in preventing and treating cancer,” she said.
Don’t despair if your local market doesn’t stock black trumpet, maitake or even shiitake. For every mushroom featured in “Shroom,” Selengut offers substitutions.
Whether you’re a neophyte or longtime mushroom consumer, you’ll want to check out “Shroom” for its informative and lively look at selecting, cooking and enjoying this fabulous food.
Sweet Potato Soup With Lime Leaves, Beech Mushrooms, Basil and Peanuts
Recipe from “Shroom” provided by Becky Selengut. The beech mushrooms are less the star here and more of a textural element used as a garnish. Because of this, it’s extra important to use homemade mushroom stock to highlight the mushroom flavor. This soup started in my mind’s eye somewhere in Thailand (lime leaves, basil) and then — somewhat inexplicably — migrated to West Africa (sweet potatoes, peanuts). This is the perfect kind of soup to serve when it’s raining, you’re snuggled up on the couch with a blanket, a fire is lit, Thai music is playing and a zebra is running through your living room.
Prep Time: about 10 minutes (if not making mushroom stock from scratch)
Cook Time: 45 minutes
Total Time: 1 hour
Yield: 4 servings
Wine pairing: French Riesling
3 tablespoons coconut oil, divided
1 small yellow onion, small diced (about 1 cup)
¾ teaspoon fine sea salt, divided
2 pounds orange-fleshed sweet potatoes, peeled and large diced
5 lime leaves (substitute 1 teaspoon finely grated lime zest)
¼ cup white wine
5 cups mushroom stock (see recipe below)
1 tablespoon seasoned rice wine vinegar, plus more as needed
1 tablespoon fish sauce
7 ounces beech mushrooms, base trimmed and broken apart into bite-size clumps
½ cup lightly packed fresh Thai basil
⅓ cup roasted, salted peanuts, chopped
Chili oil (see recipe below) or store-bought Asian chili oil, for garnish
1. In a soup pot over medium-high heat, melt 1½ tablespoons of the coconut oil. After a moment, add the onion and ¼ teaspoon of the salt and sauté for 10 minutes, until starting to brown. Add the sweet potatoes and lime leaves. Sauté for 2 to 3 minutes, then turn the heat to high, add the wine, and deglaze the pan, scraping up any brown bits. Add the stock, bring to a boil and then lower the heat to a gentle simmer. Cook until the sweet potato cubes are tender, 20 to 25 minutes.
2. Add the rice wine vinegar. Remove the lime leaves. Puree the soup in a blender until very smooth, or puree in the pan using an immersion blender. Season with the fish sauce, another ¼ teaspoon salt and more rice wine vinegar. If you feel it needs more salt, add more fish sauce (a little at a time). Keep tasting until it’s right for you.
3. Meanwhile, prepare the beech mushroom mixture. In a large sauté pan over high heat, melt the remaining 1½ tablespoons of coconut oil. After a moment, add the mushrooms and the remaining ¼ teaspoon salt. Toss the mushrooms around in the oil, and then spread them out. The idea is to get them to release their liquid and brown quickly. When they brown, stir in the basil and peanuts and transfer to a small bowl.
4. Serve the soup in wide bowls, garnished with the mushroom mixture and drizzled with chili oil.

You won’t be sorry you took the time to make your own. As you cook and are busy prepping vegetables and such — carrots, celery, onions, mushrooms, parsley, thyme — save the trimmings instead of tossing or composting them. (Skip vegetables such as kale, cabbage, broccoli or anything with a dominating flavor or color that you wouldn’t want in a mushroom stock — no beets!)
To make the stock, add these vegetable scraps to a quart-size resealable plastic bag that lives in the freezer. When the bag is full, you are ready to make your stock. At the market, pick up a small onion, a handful of fresh shiitake mushrooms and some dried porcini. Preheat the oven to 400 F. Drizzle a little high-heat oil on a rimmed baking pan. Throw the shiitakes, along with the chopped-up onion, onto the pan, and toss with the oil. Roast until caramelized, about 20 minutes. Deglaze the pan with a little wine or water, scraping up any brown bits stuck to the pan. Dump the mushrooms and onions, along with the liquid, into a stockpot along with the contents of that freezer bag (no need to thaw) and a few rehydrated pieces of dried porcini (along with the strained soaking liquid). Cover with 3 quarts water, chuck in about 5 peppercorns, bring to a boil, lower to a simmer, and cook, uncovered, for 45 minutes. Pour the contents of the pot through a fine-mesh strainer set over a large bowl, pressing on the solids to extract as much liquid as possible. You should end up with about 2 quarts mushroom stock.
Want to make vegetable stock? Do the same thing, but just use fewer mushrooms and more vegetables (and a big flavor bonus if you roast some of the vegetables as you would the shiitake and onion). If you want to make mushroom stock but don’t have a full bag of trimmings in the freezer, just use an assortment of vegetables and mushrooms (equaling roughly 1 quart) and follow the same general procedure. See the video on making mushroom stock at www.shroomthecookbook.com.

You can find many varieties of bottled chili oil in Asian markets or online, but it’s ridiculously easy to make a batch from scratch and store it in your fridge. Plus, your homemade oil contains none of the additives and preservatives that are commonly added to the bottled versions. To make your own, in a small saucepan set over medium heat, combine 1 cup peanut or coconut oil, along with 3 to 5 tablespoons red pepper flakes (see note). (The quantity will depend on how hot you want the oil to be.) Heat the oil to 300 F on an instant-read thermometer. Remove the pan from the heat and try not to breathe in the fumes!
Let the oil cool to 250 F, and then add 1 tablespoon toasted sesame oil and 2 tablespoons minced, roasted, unsalted peanuts. Transfer to a clean glass jar with a tight-fitting lid. Add 1 teaspoon salt and 1 teaspoon sugar. Seal the jar, shake it a few times to distribute the ingredients and leave at room temperature for 2 days. Refrigerate. It will keep for at least 1 month, if not longer, in the fridge.
Note: You can purchase whole dried chiles, toast them in a dry pan until flexible and fragrant, and then pulse them in the food processor, or just use regular bottled red pepper flakes.
