Soup and bisque are both liquid-based dishes that are eaten with a spoon. However, there are some differences between them. Here are the key differences and similarities between soup and bisque:

Bisque

• Bisque is a type of soup that is traditionally made from crustaceans like lobster, crab, or crayfish.
• It is a smooth, creamy soup that should include a stock made from the shells, a large amount of cream, and a thickening agent made from either finely-ground shells or rice.
• Bisques are typically made with seafood, while soups cover a broader range of ingredients.
• Bisques are thicker than soup and have a smooth, velvety texture.
• Bisques are often considered to be a luxurious dish.
• Bisque is typically served as an appetizer.

Soup

• Soup is a category of food that’s mainly liquid-based.
• Soups can include a variety of ingredients such as veggies, pasta, grains, and different kinds of meat and fish.
• Soups can vary in texture from chunky to puréed.
• Soups are more flexible in terms of ingredients than bisques.
• Soup is more versatile, and can be served as an appetizer, main course, or even a light snack.

In conclusion, bisque is a type of soup that is typically made with seafood and has a smooth, creamy texture. Soup, on the other hand, is a broader category of liquid-based dishes that can include a variety of ingredients and textures.
