In a large non corrosive soup kettle, combine the tomatoes, peppers, celery, onion, garlic, bay leaves, brown sugar, and vinegar. Simmer over low heat, stirring occasionally, for 1 hour. Stir in the cinnamon, cloves, ginger, mustard, and cayenne pepper. Continue to simmer over low heat for 2 hours. Stir regularly with wooden spoon to prevent scorching. Add the black pepper and salt to taste. Remove and discard the bay leaves. Cool and ladle into clean, hot, half pint jars, leaving a 1 cm head space. Seal and process in a water bath for 10 minutes.
