Pleurotus ostreatus var. columbinus

Blue Oyster

Ye ole faithful of the gourmet mushrooms.

The short version

Like a way better version of the grocery store mushroom. Use it anywhere a recipe calls for button or cremini. Keep the heat moderate, since too high changes the flavour.

This bio has been the hardest for me to write. In my mind, the blue oyster is a little bit of everything that you see in the other bios, which unfortunately has the effect of making it a bit more difficult to succinctly describe as its own thing.

Being that I do have to describe it though, the blue is the quintessential gourmet mushroom; it's not doing anything too crazy but with one bite and you know you're not really in Kansas anymore when it comes to mushrooms. I often describe it to people at the farmer's market as like a way better version of your typical grocery store mushroom.

What I mean by this is that it's got more umami than a cremini, but less so than a shitake. It's meatier than a button, but less so than a Black Pearl or Pink. It's cooler looking than a portobello, but isn't as vibrant as a Golden. It's kind of a totally different thing than a Lion's Mane so I don't really know how to compare those too, but you see my point.

As such, this one is kind of the standard replacement for buttons or creminis. Whenever a dish calls for either brown or white, go for blue - which is actually more of a grey by the time they're harvested, but I digress. Actually, it is a real shame nobody gets to see them when they first start growing, because it's such a cool blue color you don't really see in any other food. The picture doesn't really capture it, but see what I mean?

Anyways, I don't know if I would say that the blue is my favorite, but it's definitely the one I reach for the most. Does it make sense to describe a mushroom as reliable? That's how it feels, it's just always there for you when you don't want to think about it too much. It's the standard, and I don't think I've touched a grocery store mushroom since I started growing these years ago (and I've had some customers echo a similar sentiment!)

My only piece of advice with this one is try not to cook it on too high of a heat. I feel like it changes the flavour, but maybe that's just me
