Directions:

1. Slice the peppers in half lengthwise; remove stem, seeds and membrane. Place under the broiler skin side up until the skin turns black and blisters. Remove and immediately place in a small paper bag or plastic container with a tight lid. Place in the freezer for 10 minutes; this will loosen the roasted skin. Remove peppers and rub off the black skin with your fingers. Chop skinned peppers and set aside.

2. Saute the butter, onions, and garlic until soft in a heavy bottomed soup pot on medium-low heat. Add the reserved red peppers, tomato paste, and chicken stock. Bring to a low boil, reduce the heat, and then simmer for 10 minutes. Stir in the heavy cream, cilantro, salt, and pepper. Stir in the cornstarch mixed with a little cold water to thicken. Simmer 5 minutes. Let the soup cool slightly, and then blend in batches in a blender, or use an immersion blender to puree. Sprinkle the cilantro leaves on top.
