One of my favourite soups to make at home is tom yum soup. I learned a version of it at the Chiang Mai cooking school and never looked back since. It’s dead easy to make from scratch and even adding tom yum paste is optional. Granted, the ingredients aren’t the easiest to find, but I’m finding that more and more shops are stocking them. Some of my local supermarkets even sell tom yum starter packs with lemongrass, galangal, kaffir lime leaves, garlic, shallot, lime and chilli in them. What I normally do is buy a bit more of the herbs when I see them, prepare them and chuck them in the freezer. With a bit of forward planning, a fragrant spicy soup can be made from frozen to tummy in minutes. If you’d like the soup a little spicier, there’s no need to add more chilli, just pound the chilli padi into smaller bits.
For today’s soup, I had some seafood and plenty of prawns and their shells. I also had some spare chicken bones and made a lovely stock from boiling the bones and the prawn shells and heads together for about 10 minutes. The prawn heads, especially when I squeezed out the orangey guts, gave the stock an intensely briny prawn flavour. You can make the soup with plain water, it’ll still be fragrant but not as robust.
15 prawns, shelled
1 large squid, prepared
1 clove garlic, smashed and peeled
1 shallot, peeled
2 thick slices galangal
2 kaffir lime leaves
3 stalks lemongrass, cut diagonally into thick slices
1 chilli padi, smashed
1 small punnet cherry tomatoes (about 16)
1 small bag oyster mushrooms (about 12), torn into large chunks
juice of one big lime
2 tbsp fish sauce
1 bunch coriander, leaves only
- Make stock from the prawn shells and head by boiling them in 2 litres of water for 1o minutes. Strain the stock into a separate pot for making soup.
- Add the garlic, shallot, galangal, kaffir lime leaves, lemongrass and chilli padi to the stock and bring to a boil. Next, add the prawns, squid, tomatoes and mushroom and bring to the boil again.
- Off the heat, add the lime juice and fish sauce sparingly, tasting as you go along, till you get the right balance of sour and salty.
- Serve, garnishing with coriander leaves.
