Peppers can be roasted whole or halved, on an open flame or oven. Brush them with olive oil and lay them on the grill or on a cookie sheet in a 500 degree oven until the skin begins to darken and pull away from the flesh of the pepper. At this point turn them and repeat the blackening on another side. Once the pepper is roasted all around put it immediately into a paper bag for 10 minutes, this steams the pepper further and make removing the blackened skin easier. Remove from the bag to a bowl of very cold water and remove the skin. Roasted peppers can be laid out flat and stacked with waxed paper between each layer. Once you have 5-10 peppers slide them into a zip lock and freeze for the winter.
