The king trumpet, eryngii or king oyster mushroom is the largest of the oyster mushroom genus and, unlike other oyster mushrooms, their stalks aren’t tough and woody to eat. Instead, they're hailed for their meaty texture and umami flavour. These mushrooms average between 4-6 inches in length, has a long shelf life in the fridge (roughly one week) and doesn’t lose its shape when cooked. The texture is sometimes likened to abalone or scallops, which makes them an option for vegetarians and are often billed as ‘mushroom steaks’ or ‘vegan scallops’.
