Heat oil in a large pot over medium. Add leek and celery, and sauté, stirring often, for 4 minutes or until soft and fragrant, but not browned.
Add potatoes and curry powder, and sauté for another minute. Add stock, pumpkin and lemon juice; stir to combine and bring to a boil. Reduce to simmer and cook, covered, for 12-14 minutes, or until potatoes are tender.
Stir in milk and cook until heated through. Season with salt and pepper. If you wish, serve each bowl of soup with a pinch of nutmeg and a sprinkle of croutons.
