Marinated Mushrooms

As a committed mushroom fanatic, I knew I was going to make these when I spied the recipe in my friend Rebecca’s book “The Ultimate Guide to Vegetable Side Dishes“. The method was one I hadn’t tried before, but it truly paid off.

These marinated mushrooms don’t turn odd colors, become slimy, or get funky aromas because of the quick swim they take in simmering water. It not only helps preserve the mushrooms a little longer, but it also makes the texture better.

A batch will stay good for at least a week in the refrigerator, if you ever manage to stretch them out that long! It is not advisable to freeze them, though, as they may give off a lot of liquid and become tough when thawed.
