Marinated Portobello Mushrooms


"Portobello mushrooms marinated in balsamic vinegar and rosemary, then grilled - these are heaven. If you don't have a grill, they're also delicious fried in a skillet. Portobello mushrooms are extremely large, dark brown mushrooms that are simply the fully mature form of the crimini mushroom, a variation of the common white mushroom."

I made it again and made changes so I guess it isnt the same at all. I used white wine instead of the vinegar and added basil and garlic.

Don't marinate more than 30 minutes, because they'll get a bit too tart. Otherwise these were very good.

I marinated the mushrooms for 30 minutes and they were simply too tart for my family's taste. Also, four tablespoons of dried rosemary was too much. The mushrooms were covered in crunchy rosem...
