Step-by-step explanation:
The chilled potato and leek soup in question is traditionally known as vichyssoise. This soup is characterized by its creamy consistency and is typically served cold. It is not to be confused with minestrone, which is a hearty vegetable soup with pasta or rice usually served hot, nor with gazpacho, which is a cold soup made of raw blended vegetables, or chowder, which is often thicker, made with milk or cream and with chunks of seafood or corn.
Vichyssoise is an elegant soup, which is said to have been invented by a French chef at the Ritz-Carlton in New York City during the early 20th century. The classic recipe involves pureeing cooked leeks, potatoes, cream, and chicken stock, and then chilling the mixture. This soup is known for its smooth texture and subtly balanced flavors from the leeks, potatoes, and cream.
In summary, the final answer to the question about the name of the chilled potato and leek soup is vichyssoise. The soup's refined characteristics make it a timeless French-inspired dish that can be enjoyed during warmer seasons or as a sophisticated starter.
