Southern Indian Rice & Seafood Soup

This soup was first cooked for me by Das, my friend who runs the southern Indian restaurants in London called Rasa. I've based mine around his original recipe, and what's fantastic about it is that it's so easy to make. It only takes about 30 minutes, and the other great thing is that the ingredients are not particularly expensive, so it's economical. However, if you want to spend a little more and make it a bit luxurious using something like crab, then you can. The soup is just as good with frozen prawns and flaky white fish though. Use any selection of fish that you fancy – I like to use a good mixture of fresh-looking fish (John Dory, cod, haddock or red mullet all work well). Get it skinned and filleted, then all you have to do is chop it up. If you can find any coconut oil, use that, otherwise vegetable and sunflower oil are fine to use. This really is one of my favourite soups. It's not too hot, but as you eat it you can pick out the individual flavours. And there's something about having rice in a soup that makes it really scrumptious.
