Mushroom Conserva

Keri Bevan
Mushroom conserva, aka pickled mushrooms, are such a wonderful delicacy, it's a shame that people don't make them more often. They make a wonderful topping for crusty bread or polenta, and a worthy addition to a charcuterie board.

Ingredients
 
 

  • 1 pound mushrooms
  • 2 cloves garlic minced
  • ¾ cup olive oil + 2 tablespoons divided
  • 1 teaspoon salt divided
  • ½ teaspoon chili pepper flakes
  • 2 tablespoons fresh rosemary leaves finely chopped
  • ½ cup rice vinegar
  • 2 teaspoons maple syrup

Instructions
 

  • Heat 2 tablespoons of olive oil over medium-low heat in a Dutch oven, or a heavy bottomed pan.
  • Add the mushrooms and ½ teaspoon of salt. Reduce the heat to low, cover the pan and allow the mushrooms to release their liquid for 5 minutes.
  • Uncover the pan and saute the mushrooms for a further 5 minutes or until they're fully browned. Using a slotted spoon, remove the mushrooms from the pan and transfer to bowl.
  • Wipe the pan out and heat 1 tablespoon of oil in the skillet over low heat. Saute the garlic, chili pepper flakes, and rosemary for 30 seconds. Take the pan off the heat and allow it to cool for 3 minutes.
  • Add the vinegar, maple syrup, ½ teaspoon of salt, and ¾ cup of olive oil to the pan. Stir to combine.
  • Return the pan to the stove and heat the mixture through over very low heat, approximately 2 minutes.
  • Put the mushrooms in the bottom of a 1 pint jar. Pour the liquid over the top.
  • Using a chopstick, stir the mixture gently, to release any air bubbles.
  • Put the top on the jar.

Notes

  1. The best mushrooms to use for making conserva are meaty mushrooms with a firm texture, such as porcine,cremini, or Portobello mushrooms. These types of mushrooms hold their shape well during the preservation process and have a robust, earthy flavor that is well suited for marinades. Shiitake mushrooms are also a great option for conserva, they have a distinct, savory flavor and a meaty texture. You can also use wild mushrooms to make conserva, such as chanterelles, morels, and boletus. These mushrooms have a more delicate texture and a unique, earthy flavor that can be preserved and enjoyed in a variety of dishes.
  2. Kept covered in oil, the mushrooms will stay fresh in the fridge for up to 1 month.
