Reddit reviews The Joy of Pickling: 250 Flavor-Packed Recipes for Vegetables and More from Garden or Market (Revised Edition)

I have this book and on page 148 is a recipe I plan on trying this weekend. It's a fridge recipe, and says should keep for about 2 months in the fridge.

• 1 pound small button mushrooms (I bet yours would be fine)
  
• 2 teaspoons pickling salt
  
• 6 tablespoons red wine vinegar
  
• 2/3 cup red wine
  
• 1/2 teaspoon sugar
  
• 4 whole cloves
  
• 8 whole black peppercorns
  
• one 1-inch piece fresh ginger, sliced thinly
  
• 1 Mediterranean bay leaf
  
  toss mushrooms with salt, put into a flat bottomed dish and cover with plastic wrap. Let stand at room temp for 8-12 hours.
  
  put the mushrooms and juice into a nonreactive pan. cook over medium heat until all the juice has evaporated, 8-10 minutes. Add remaining ingredients. simmer the mix for 5 minutes. Remove pan from heat and let them cool.
  
  Pack the mushrooms into a 2-3 cup jar (a pint jar I would imagine....whatever it fits into...). Pour the liquid over the mushrooms. Cap the jar and refrigerate for at least two days before eating.
  
  Edit: for stupid spelling and spacing. >.<
