As requested (!) here's the recipe.... (hoping broadband holds out for a minute)
Curried Sweet potato soup
1kg sweet potatoes, peeled and cut into chunks
1 onion, peeled and chopped
Two dessert spoons of curry paste ( I only used a little and I've seen recipes that only say 1 or 1.5 TEASPOONS of curry paste so I'll leave you to judge!)
1 litre vegetable stock
Can coconut milk
Sweat onion in oil, add paste and cook for few minutes, add sweet potato and stock. Bring to boil and simmer for 20 minutes or until potato is soft. Add coconut milk. Whizz with blender till smooth.
I served it with croutons made from toasted herby bread.
Found on a website but can't find the credit - sorry whoever invented it!
