Make the marinade first (before rinsing mushrooms):
In a medium saucepan, combine vinegar, salt, sugar, garlic, bay leaves, ground black pepper, red pepper and dill. Simmer marinade for 5 minutes.
Add 2 cups water, bring to a boil and simmer another 5 minutes. Lastly, add oil and turn off the heat.
Prepping the Mushrooms and Assembly:
Boil 16 cups (4 quarts) Water with 3 Tbsp vinegar (or juice from 1 lemon) - to prevent browning of mushrooms.
Rinse mushrooms (immediately after rinsing mushrooms, cut mushrooms into quarters, halves or even whole if they are small) and place in boiling water. Stir, cover and cook 3 minutes.
Drain mushrooms and pour marinade over them. Boil another 2-3 minutes in the marinade.
Cool to room temp and refrigerate overnight then enjoy!
Enjoy!!!
