Step 1: Preparing the Vegetables
- Clean the Mushrooms: Gently clean the mushrooms using a damp cloth or paper towel. Avoid soaking them in water as mushrooms absorb moisture quickly.
- Slice the Onion: Peel and thinly slice the red onion into rings or half-moons.
- Blanch the Mushrooms: Bring a pot of water to a boil and briefly blanch the mushrooms for 1-2 minutes. This step helps them absorb the pickling brine better. Drain and set aside.
Step 2: Making the Pickling Brine
- Prepare the Brine: In a medium saucepan, combine the vinegar, water, sugar, and salt. Heat the mixture over medium heat, stirring occasionally, until the sugar and salt are fully dissolved.
- Add the Flavorings: Stir in the garlic, bay leaf, peppercorns, mustard seeds, thyme, and red pepper flakes (if using). Bring the brine to a gentle simmer.
Step 3: Pickling Process
- Combine the Vegetables: Place the mushrooms and sliced onions in a clean glass jar.
- Pour the Brine: Carefully pour the hot pickling brine over the vegetables, making sure they are fully submerged. If needed, press the vegetables down with a spoon to ensure they are covered by the liquid.
- Cool and Seal: Let the mixture cool to room temperature before sealing the jar with a tight-fitting lid.
- Refrigerate: Store the pickled mushrooms and onions in the refrigerator. Allow them to marinate for at least 24-48 hours before enjoying for the best flavor. They’ll keep well in the fridge for up to 2 weeks.
