Common examples include canapés, stuffed mushrooms, and shrimp cocktail. These bite-sized treats are typically presented on platters for guests to enjoy while mingling. Hors d'oeuvres can be simple or elaborate, depending on the occasion, and are often accompanied by drinks. They play a key role in social dining, allowing people to sample a variety of flavors before the main course.
