Ingredient Preparation

Proper preparation of the ingredients ensures that the mushrooms and onions absorb the pickling flavors well.

Preparing the Vegetables

  1. Clean and Trim the Mushrooms: Ensure the button mushrooms are cleaned and trimmed of any excess stems. You want them to be bite-sized for easy pickling and eating.
  2. Slice the Onions: Thinly slice the onions, aiming for even slices. This helps the onions pickle at the same rate and ensures a consistent texture.

Instructions

Sterilizing the Jars

  1. Sterilize Jars and Lids: Before packing the vegetables, sterilize the jars and lids by boiling them in water for 10 minutes. This step is crucial for preventing any bacteria from spoiling your pickles and ensures a long shelf life.

Packing the Jars

  1. Pack the Vegetables: Tightly pack the cleaned and trimmed mushrooms and the sliced onions into the sterilized jars. Make sure to leave about 1/2 inch of headspace at the top of each jar to allow for proper sealing.

Preparing the Brine

  1. Make the Brine: In a large pot, combine the white vinegar, water, sugar, salt, garlic, mustard seeds, black peppercorns, coriander seeds, and bay leaf. Bring the mixture to a boil, stirring until the sugar and salt are fully dissolved. This brine will infuse the mushrooms and onions with its vibrant flavors.

Adding the Brine and Sealing

  1. Add the Brine: Carefully pour the hot brine over the packed vegetables in the jars, ensuring they are fully submerged. Leave about 1/2 inch of headspace at the top of each jar.
  2. Seal the Jars: Wipe the rims of the jars clean with a damp cloth to ensure a good seal, then place the sterilized lids on top. Screw on the bands until they are fingertip-tight.

Processing the Jars

  1. Process the Jars: Place the sealed jars in a large pot of boiling water, ensuring they are fully submerged. Process the jars in the boiling water bath for 10 minutes. This step helps to seal the jars properly and extend the shelf life of your pickled vegetables.

Cooling and Storing

Cooling and Storage

  1. Cool the Jars: After processing, carefully remove the jars from the water bath and let them cool to room temperature. Once cooled, check that the lids have sealed properly by pressing down in the center. If it doesn’t pop back, the jar is sealed.
  2. Store: Store the sealed jars in a cool, dark place. The pickled mushrooms and onions will last for several months when stored properly. Once opened, refrigerate the jars and ensure the vegetables remain submerged in the brine to maintain freshness.

Allow Flavors to Develop

Waiting for Flavor

For the best results, allow the pickled mushrooms and onions to sit for at least a week before consuming. This gives the vegetables time to fully absorb the flavors of the brine, resulting in a more intense and delicious taste.

Variations

Customizing Your Pickled Vegetables

This recipe is flexible and can be adjusted to suit different tastes:

  • Spicier Version: Add a teaspoon of red pepper flakes to the brine for a bit of heat.
  • Different Vegetables: Try adding sliced carrots, bell peppers, or cauliflower for a pickled vegetable medley.
  • Herbal Twist: Include fresh dill or rosemary in the brine for an added herbal note.

Unopened jars can last for several months when stored in a cool, dark place. Once opened, refrigerate and consume within a few weeks.

Yes, you can use a variety of mushrooms, such as cremini or shiitake, but button mushrooms are ideal because they hold up well during the pickling process.
