Getting to know...Blue Oyster

The Blue Oyster mushroom is quite similar to the Pearl or Snow Oyster mushroom, Pleurotus ostreatus. It is also often considered a variant of it as well, the Pleurotus ostreatus var. columbinus. 

The Blue Oyster has similar nutrients and health benefits as a result. The main visual difference is the smoky blue or bluish-grey look of the caps when they mature. The Blue Oyster also has a nice smooth transition from the top of the cap to its underside, also known as an even cap margin. Along with being speedy, simple growers and having a unique but pleasant visual appearance, these mushrooms are one of our top sellers.

This mushroom contains potassium and antioxidants like the Pearl Oyster, which is explained more here.

Oyster mushrooms are also a source of protein. One cup of these mushrooms contains about five grams of protein, which can help build and repair body tissue and ensure the body runs the way it’s supposed to. They only contain less than one gram of fat and are an effective source of energy with around 10g of carbohydrates. The mushrooms are a source of folate as well, which helps turn carbohydrates into energy, make red and white blood cells, and produce DNA. 

Fun fact: Sea oysters live in groups and clusters called colonies or oyster reefs. The Blue Oyster mushrooms grow similarly to their mollusk mates, in clusters, either in a shelf-like shape in the wild, or close together when growing towards the air in mushroom grow kits. 

Meal options: The Blue Oyster mushrooms taste similar, if not identical, to Snow Oysters, with a unique, mild earthy and anise flavour. With a slightly meaty texture, the mushroom caps taste well when stir-fried and add another depth of flavour to soups and pasta. Check out a pasta recipe here that pairs the mushrooms well with a creamy sauce.

Disclaimer #2: These Blue Oysters are delicious mushrooms, not a rock band. There are also no studies (yet) on what more cowbell would do to Blue Oyster mushrooms.
