Heat the oil in a large saucepan over medium heat. Add the onion, carrot, and potato. Cover and cook for 4 minutes to soften. Stir in the celery salt, broth, corn, and salt and pepper to taste. Bring to a boil, then reduce the heat to a simmer, stir in the coriander, liquid smoke, and almond milk, and cook, stirring frequently, for 5 minutes.
While the soup is simmering, combine the drained cashews and chipotle in a blender with 1 cup of the simmering broth from the soup. Blend until smooth and creamy, then add 1 more cup of the soup and blend until smooth.
Stir the mixture back into the soup.
Taste and adjust the seasonings. Ladle the soup into bowls and garnish with parsley and pimientos.
