Sweet potato, coconut & coriander soup

March 6, 2013 by lizayling 3 Comments

sweet potato, coconut & coriander soup

If I lived near to Russia’s meteorite crater, I’d think this was a lump of outer space rock. Known on earth as a sweet potato, despite its rough, off-putting exterior, it makes a warming bowl of comfort soup on this gloomy Malta day. Combined with coconut and coriander, it speaks of South American flavours, lifts the soul and certainly makes a no-frills, easy main course soup.

Sweet potato, coconut & coriander soup

Most sweet potatoes I’ve come across are smaller, elongated and have flesh in shades of orange. Baffled by the basket of huge muddy lumps, I asked the market stallholder what they were; apparently these are a less commonly grown variety of white-fleshed sweet potatoes. I’ve not seen them in Malta before. They were huge and round, somewhat difficult to peel (as are all sweet potatoes, I find, so mind your knuckles!) but yielded an impressive amount of soup ingredient.

Sweated down with some leeks, a handful of fresh-chopped coriander and then combined with some stock and a can of light coconut milk, the potatoes created a creamy, thick soup that was sweet but not too sweet and dreamily tasty. In Malta, market stall veg comes clad with soil and is not manicured for sale like supermarket fare. Don’t be put off by the exterior of sweet potatoes; they have impressive nutritional value compared to any regular potato, to which they are only a distant relative.

As I made this, I thought it would be my last wintry soup for the year, but with the blustery grey skies outside my window now, in early March, I have a feeling I’ll be cooking up this tuber as comfort food a while longer. And when BBQ season starts, I’ll try it sliced and griddled with herbs. Sweet potato crisps sound tempting.

Smooth and warming but light enough soup for spring and summer. Fragrant and tasty for a lunch or as a starter.
Author: The Red Bistro
Recipe type: Starter, Light Lunches
Cuisine: International
Serves: 4-6 servings
Ingredients
  • 1 large sweet potato or 2 medium-sized, peeled and cut into 1-2 cm cubes
  • 2 leeks, trimmed and sliced finely
  • knob of butter
  • 2 tbsp olive oil
  • 1 x 400ml can coconut milk (you won’t need it all)
  • handful of fresh coriander, finely chopped + some to garnish
  • 1 tsp dried coriander seeds
  • 500 ml water or stock
  • freshly-ground black pepper & sea salt to season
Method
  1. Gently heat the butter and olive oil in a heavy-based pan over a low-medium heat.
  2. Add the diced sweet potato and leeks, the crushed coriander seeds and just a little of the chopped coriander. Sweat off the vegetables gently, ideally with a lid on the pan, until leeks are tender and slightly translucent. Toss around a bit to stop potato sticking.
  3. Add the water or stock, and 250 ml coconut milk (retain some to water down soup later on to your desired consistency). Season.
  4. Simmer for around 10-15 minutes until the sweet potato is tender.
  5. Adjust with more coconut milk or stock/water for your desired consistency.
  6. Remove from the heat, leave to cool a little, then blend. You can keep the diced vegetables unblended or just blend half the soup as desired – I blended the lot, but it’s up to you.
  7. Reheat gently to serve. Garnish with some chopped coriander and a swirl of coconut milk.

    Tried this last night. I used 100 ml coconut milk, and added 125 ml single cream to the blended mixture which made it nice and creamy. However, I found that the finished product had a sweet taste, so added the juice of one lime to the mixture before serving. Magnificent – it gave that extra little kick that that the soup and fresh coriander needed!

      Hi Pat,
      That’s a wonderful idea with the lime as it completes the Asian inspiration of the soup nicely. I have made it twice now and with different types of sweet potato and the white variety was far sweeter. I used light coconut milk and stock to water it down a bit as potato can be thick. I like coconut milk but in moderation. It can, as you infer, overpower things and make them too sweet. I’ll definitely try with the lime next time; I tend to use lemons a lot as limes are not always so easy to find when I want them! Love them though!

    Hi i found this recipe to be amazing!. I did add a small extra to give it a kick; and enhance the flavours. I liked the hearty nature of this soup in the fall – very authentic, all from mother earth. A very classy soup that to be fair could be implemented at any time of year, especially the autumn/ Winter

    Sweet potatoes are a great source of Vitamin A; also vitamin C to aid the immune system. Also fundamentally a great source of Vitamin B1 B2 B12 ( which help to convert food into fuel) keeping us energised.
