This is a wonderfully indulgent appetizer! I sometimes roast 2 heads (not cloves) of garlic and let my guests spread some garlic on the bread before spreading the cheese on...divine!! Tho the recipe calls for brie in a box, I usually buy a round of Brie and put it into a small oven-proof dish. I have also used minced green onions instead of the shallots with good results. If the baby bella shrooms are large, cut them into quarters.To cut the top off the round of Brie more easily, first place the cheese in the freezer for a few minutes to firm it up slightly. If you can get a sour dough baguette in your neck of the woods I highly recommend it! This is adapted from a recipe of Rick Rodgers.
