From Chef Oonagh Williams of Royal Temptations Catering
This recipe came from a client who said that her family devoured it. I altered proportions to my taste and added garlic and bay leaf as well as coming up with other options.
1. Combine all ingredients except mushrooms in a stainless steel or non-stick saucepan, bring to a boil, reduce heat and simmer for 5 minutes.
2. Add mushrooms, bring back to boil and simmer, covered, for 5 minutes.
3. Remove from heat, pour into glass or similar non-reactive dish, cover and chill.
4. Marinate for at least 4 hours.
Tips and Alternatives:
These mushrooms are best served at room temperature. They are a wonderful part of an antipasto platter or side dish with grilled meat. I also substitute 1 lb. thawed pearl onions for mushrooms and cook for about one hour to make an addictive onion relish/chutney. It goes great on gluten-free French bread with cheese.
If the mushrooms are too vinegary for you, then reduce the vinegar by 1 Tbsp. next time, or add some more sugar to blend until it dissolves.
