National Seafood Bisque Day is observed worldwide on October 19 each year. This day celebrates bisque, a smooth and creamy soup of French origin, typically made with seafood such as crab, lobster, crayfish, or shrimp. Traditionally, bisque is a highly seasoned soup based on a strained broth of seafood, originally made from imperfect crustaceans not suitable for market sale. While modern bisque is often thickened with rice, authentic recipes used thinly ground shells for this purpose. To commemorate the day, people can enjoy bisque at restaurants or prepare it at home, with recipes such as clam bisque that include ingredients like chopped onion, butter, flour, and half and half.
