Wonderful! I used orange-fleshed sweet potatoes (yam?) and because I didn't have red curry paste, substituted laksa paste - I don't think this detracted from the character of the soup at all. Will definitely make again.
Simply divine, although I have to admit I did one major change and blended everything together at the end with my immersion blender. I didn't have any red curry paste so I added some garam masala instead. The soup has a wonderful flavor. The garam masala added a wonderful bang to the back of the throat. I've already made up a second batch, tripled the recipe and froze it for a treat for when we drag ourselves home after a gruelling day at the office. Thanks for the recipe!
