These mushrooms are not only delicious, but they require no cooking! Simply mix all of the ingredients together and allow them to marinate for 3 days. Serve as a side dish, appetiser or a snack.
Monosodium glutamate can be purchased online or at any Asian/Oriental speciality store.
I rated this a 4 as is, but I make a version that my family & friends give a 5 with giant portobello caps, which I marinate and then grill. My 17-year-old daughter asks for them about 3 times a week! I eliminate the salt, sub honey for sugar, use fresh oregano, omit the msg, use 1 tablespoon minced garlic, sub balsamic vinegar, reduce the pepper to 1/8 tsp and add about 1/4 c. soy sauce (hence the omitted salt, tho I add fresh-ground sea salt at the table), about 1/2 teaspoon minced fresh ginger, and a Tbs or so of chopped scallion if I have any on hand. I haven't marinated as long as 3 days; 24 hours seems plenty. I've also thrown in large pieces of bell pepper and chunks of zucchini, all of which have been a big hit among family & guests (including a lot of my daughter's teenaged friends). - 25 May 2010 (Review from Allrecipes US | Canada)
I make something like this for summer potlucks, only I don't use MSG, I double the spices and I use a couple tbsp. of balsamic vinegar instead of white vinegar. I could eat the whole bowl. You're best of doubling this at least. This recipe is good with baby bellas, too. - 24 May 2010 (Review from Allrecipes US | Canada)
