Small, egg-shaped tropical mushroom grown on rice straw. A staple in Asian and tropical-African cooking, usually found canned in the West.
Affordable canned protein from the Asian-grocery aisle that travels well into Black American kitchens through stir-fries and one-pot dishes. A cheap pantry mushroom for stretching meals.
Straw mushrooms are relatively high in protein and contain volvatoxin and beta-glucans studied for immune-modulating and mild antitumor activity, though human evidence is limited. Fresh straw mushrooms carry vitamin C, unusual among fungi, but the canned form most people buy loses much of it. They provide ergothioneine and potassium with very few calories, making them a useful low-calorie protein extender. Honest note: the antitumor claims come mostly from cell and animal studies; treat straw mushrooms as nutritious food, not a therapy.
Fresh straw mushrooms are highly perishable and rarely sold in the US; canned are the norm. Rinse canned mushrooms to remove brine, then add to stir-fries, soups, and curries near the end of cooking. They cook fast and turn slippery-tender.
