Lacto-fermented mushrooms are the BOMB! Fermented mushrooms taste great on scrambled eggs, salads, and as a side to pretty much any dish. Not to mention, it is an extremely easy recipe to make. You can save time by using store-bought sliced mushrooms and a packaged pickling spice.
Put all the ingredients in a jar or fermentation crock, top with a fermentation weight, and then wait for up to four days. Give them a quick taste test and pop them in the fridge when they have reached your desired flavor.
Lacto-fermented mushrooms have an earthiness flavor as well as salty and savory that really comes through, and of course a little funkiness from the ferment. The flavor is intense and can be used as a next-level umami pop in any dish.
