Preheat to 400 degrees F.

Rinse and drain the escargots.

In a saucepan, over medium heat, combine the red wine, mirepoix, bay leaf and peppercorns. Bring the liquid to a simmer. Poach the escargots in batches for 15 seconds. Drain, set aside and reserve 2 tablespoons of the liquid.

In a small mixing bowl, combine the butter, garlic and parsley. Mix well. Season with salt and pepper. Season the escargots with salt and pepper, and place in the escargot mold. Place 2 heaping teaspoons of the butter mixture on top of each escargot. Place the molds on a baking sheet and place in the oven. Cook for 6 to 10 minutes, or until the butter is bubbly. Remove and serve with the crusty bread.
