I start looking for oysters (Pleurotus sp.) in lowland forests as soon as the temperature begins to warm and a few days after the first good rains. Some years I find them as early as late February though April is more typical. They'll keep fruiting throughout the spring and sometimes well into summer if regular rain continues, and then again in the fall.
The saprophytic oyster mushrooms in the Northwest will usually be found in association with dead red alder or cottonwood. They look like clam shells growing off the sides of standing snags or fallen trees. Fresh specimens are creamy white, with hues of pink or tan. They have gills and stems that are off-center.
While you can buy farmed oysters at the market, I find the wild variety to be more flavorful, and I use them in all kinds of dishes from around the world, east and west. My go-to recipe of recent years has been a quick, delicate Chinese stir-fry that will appeal to those who prefer a less spicy Cantonese style, which allows the oysters to really shine. If you're vegetarian, skip the chicken or swap in tofu.
3 tbsp peanut oil
3/4 lb oyster mushrooms, cut into half-dollar pieces
3/4 lb chicken breast, thinly sliced into a similar size as mushrooms
4 green onions, cut into 2-inch pieces
3 large cloves garlic, thinly sliced
1 large thumb-sized piece of ginger, thinly sliced
salt and white pepper, to taste
Marinade
1/2 tsp salt
1 tsp Shaoxing wine
1 tsp potato starch
Sauce
3 tbsp chicken stock
1 tbsp oyster sauce
1/2 tsp potato starch
2. In a wok over medium heat, sauté oyster mushrooms in 1 tbsp oil, stirring occasionally. Remove to a bowl when slightly browned.
3. Heat 2 tbsp oil in wok over high heat and add marinated chicken. When the chicken is partly cooked but still pinkish, add garlic, ginger, and green onion. Cook together, stirring, for 30 seconds until aromatic before returning oyster mushrooms to wok. Continue to cook together another minute or so until chicken is barely cooked through.
4. Pour in sauce, stir to coat, and reduce heat. Season to taste and serve immediately with rice.
