Lobster mushrooms are available on the east and west coasts of the US, but are also available online. If you can’t find them in stores or at farmer’s markets, feel free to use king oyster or oyster mushrooms instead. We’re going to start with creating a broth and adding in cubed potato to simmer and soften while we create a rich and hearty thick stew in another saucepan. Then we’re going to slowly combine them to create a rich and hearty chowdah. Top with toasty crostini or add them on the side to scoop everything up for a perfect bite.
