Heat oil in a large saucepan over medium heat. Cook the onion for 5 minutes or until soft.
Stir in curry paste for 1-2 minutes or until aromatic.
Add the carrot, sweet potato and stock. Bring to the boil. Reduce heat to low. Simmer for 25-30 minutes or until tender. Cool slightly.
Blend the soup until smooth. If it’s too thick, simply add a little water to thin it out. Heat over low heat for 2-3 minutes.
Stir in the lime juice and brown sugar. Season with salt and pepper.
Combine the sour cream, chilli and coriander in a bowl. Serve with the soup. Alternatively, just dollop a little sour cream in the middle of the plate of soup and swirl it through.
