Salsa

An unopened jar of  salsa is highly shelf stable because two of its primary ingredients--tomatoes and vinegar--are highly acidic. Acidic environments discourage the growth of both pathogenic and spoilage bacteria. Pasteurization further stabilizes salsa, making it suitable for shelf storage.
