Straw Mushroom: Cook It, and Its Deadly Twin

Straw Mushroom · เห็ดฟาง · Volvariella volvacea

Straw Mushroom — เห็ดฟาง (het-fang) — Volvariella volvacea.

Straw mushroom — het-fahng — grows on beds of rice straw, and the edible part is the young, unopened button, always cooked. In cell-culture studies, an alpha-glucan isolated from its fruiting body activated RAW264.7 macrophages. As a food, straw mushroom is a good source of protein, copper, selenium, and riboflavin. Protein helps build and maintain muscle, repairs body tissues, and helps you feel full. Copper helps your body use iron, supports normal energy metabolism, and keeps connective tissue and nerves healthy. Selenium is part of your antioxidant defenses and supports normal thyroid and immune function. Riboflavin, or B2, supports normal energy metabolism, helps reduce tiredness and fatigue, and backs your antioxidant defenses. In the kitchen, halved straw mushrooms simmer in the sour, chili-hot broth of Tom Yum Goong with prawns, or in the coconut-milk broth of Tom Kha Gai with galangal, lemongrass, and chicken; both are served over steamed jasmine rice. To grow it, pasteurize rice straw, layer it into raised beds, and add spawn. Wild-foraged lookalikes require expert identification because a deadly death cap can look nearly identical.

Safety note. Never eat wild-foraged 'straw mushrooms' unless expertly identified; the deadly death cap (Amanita phalloides) is easily mistaken for it.
