Smoked chicken, wild mushrooms, sweet basil, coconut & galangal soup

Known as ‘tom ka gai’, this soup is simple to assemble, yet contains such a complex and harmonious collection of sweet, salty, sour and spicy notes.
It only takes a few ingredients and around 10-15 minutes to make. All of the ingredients can be found easily in most supermarkets these days. This soup is also delicious using prawns instead of chicken, given the option I would still use smoked chicken stock with the prawns as the richness of the chicken stock makes for a delicious final product. To lift this exceptional bowl of soup to new heights garnish with a generous few tablespoons of nahm prik pao, chilli jam (recipe here) before serving.
Ingredients:
1 chicken breast, skin and fat removed, sliced into rough 2cm by 2cm pieces (instructions for smoking in the method)
1/4 butternut squash (roughly 50g), peeled and sliced into rough 2cm by 2cm pieces (pumpkin can be used instead)
8 Thai shallots, peeled and slightly bruised in a pestle
2 green bird's eye chillies, bruised in a pestle
2 kaffir lime leaves, torn slightly
2 sticks lemongrass, chopped into 2cm long pieces and bruised in a pestle
10g galangal, peeled and chopped into 2cm long pieces and bruised in a pestle
2 coriander roots, cleaned, washed and bruised in a pestle
½ teaspoon coarse sea salt
2-3 tablespoons fish sauce (soy sauce if vegetarian)
200ml chicken stock (vegetable stock if vegetarian)
300ml coconut cream
10g Thai sweet basil (normal basil will do)
50g assorted wild mushrooms (such as enoki, shiitake, and shimeji mushrooms)
1 lime, juiced
2 tablespoons nahm prik pao, chilli jam (for garnish)
Method:
Smoking the Chicken: To cold smoke the chicken, you'll need smoking wood chips, a large deep pan, a colander, and cling film. Place a small handful of wood chips into the pan and heat until alight. Extinguish the flames with a little water to create smoke. Quickly place the chicken in the colander, set it over the smoking pan, and cover tightly with cling film. Leave for at least 2 hours, or overnight for a richer smoky flavour.
Prepare the Squash: In a small saucepan, bring water to a boil, submerge the squash, and simmer for 3-4 minutes until soft but not fully cooked. Set aside.
Create the Soup Base: In a medium saucepan, combine chicken stock, 100ml of coconut cream, 2 tablespoons of fish sauce, sea salt, galangal, coriander roots, bird's eye chillies, lemongrass, lime leaves, butternut squash, Thai shallots, and mushrooms. Bring to a simmer.
Cook the Chicken: Add the smoked chicken pieces to the simmering soup and cook gently for 4-5 minutes until the chicken is cooked through and the vegetables are tender.
Finish and Serve: Stir in the remaining coconut cream and sweet basil. Divide the soup into bowls, garnish with chilli jam, and adjust seasoning to taste. The soup should be creamy, salty, a bit spicy, and aromatic with a hint of lime. Serve with steamed jasmine rice for a complete meal.
