✦ World's most cultivated mushroom
✦ Selenium and copper
✦ Vitamin D if UV-exposed
✦ Mild versatile flavour
White button mushrooms are the young, closed-cap form of Agaricus bisporus — the world's most cultivated mushroom. They provide selenium, copper, riboflavin, niacin, pantothenate, and potassium, and are one of the few non-animal foods to naturally produce vitamin D when exposed to UV light before sale. Their mild flavour makes them the most versatile everyday mushroom.

Preparation note
Look for the "vitamin D" claim on packaging; these mushrooms have been UV-treated and provide a meaningful plant source of D. Cook over high heat in a single layer — overcrowding causes steaming and prevents browning.
