Instructions
Prepare the Mushrooms
Fill a medium or large pot with water and bring it to a boil. Add ½ teaspoon (3g) sea salt.
Wash and dry the mushrooms. Slice in half, or quarter them if they are large.
Add the mushrooms to the boiling water and cook for 5–7 minutes, or until tender.
Prepare the Aromatics
While the mushrooms cook, slice the onion into very thin quarter circles (⅛ inch / 3mm or less).
Peel and mince the garlic.
Make the Marinade
In a medium bowl, combine olive oil, red wine vinegar, garlic, onion, oregano, parsley, red pepper flakes, and the remaining ½ teaspoon (3g) sea salt.
Whisk with a fork until well blended.
Combine and Marinate
When the mushrooms are done, drain them but reserve ½ cup (120ml) of the cooking water.
Add the mushrooms to the marinade and stir to coat.
Add just enough reserved cooking water to cover the mushrooms, then stir again.
Cover and refrigerate for 15–30 minutes, or until cool and well marinated.
Notes
These mushrooms store well in the fridge for up to 1 week.
Flavors become stronger the longer they marinate.
Enjoy them on salads, pasta, sandwiches, grilled vegetables, or as a simple appetizer.
