This page is Thai cooking for a Ballarat kitchen: cold air, a weekly shop, herbs bought the day they matter. The complete recipe is tom kha gai — chicken and galangal in a coconut soup that is still sour and salty. It is not the Geelong massaman, not the Docklands tom yum, and not a copy of the main-site tom yum goong.
Tom yum is hotter-sour and usually clearer. Tom kha is galangal-forward and coconut-rich. Ballarat weather makes the latter feel like a plan.
Goldfields shopping
You can buy coconut milk, fish sauce, chicken, limes and mushrooms in the centre. Galangal, lime leaves and lemongrass are the specialist items: grab them when you see them, slice and freeze. A paste tub in the fridge is insurance for a yellow or massaman night, fried properly, not dumped. Coriander and spring onion should be bought the day you cook; they hate a Ballarat fridge week.
Potatoes and onion are local strengths and belong in slower curries, not in this soup. Keep this recipe for chicken, mushroom and coconut. Keep a massaman for another night using Geelong’s method as inspiration only — cook from this page or from Geelong’s page, do not blend them into one brown pot.
The Ballarat hub explains why soup is a serious dish here. The tasting notes tell you a restaurant bowl should be hot through. Yours should too. Warm coconut is a failure of the saucepan, not of the climate.
Tom kha gai — chicken and galangal coconut soup
Serves four as a soup with rice. The galangal is not garnish; it is the name of the dish. If you cannot find it, you are making a coconut chicken soup with ginger, which is allowed if you rename it in your head.
Ingredients
- 4 thick slices fresh galangal
- 2 lemongrass stalks, bruised
- 6 makrut lime leaves, torn
- 400ml coconut milk
- 400ml chicken stock or water
- 400g chicken thigh, sliced
- 150g mushrooms, torn (oyster or cup)
- 2–3 tablespoons fish sauce
- 2 tablespoons lime juice, plus extra
- 1 teaspoon palm sugar
- 3 bird’s eye chillies, bruised, or fewer
- 8 cherry tomatoes, optional
- Coriander and spring onion, to finish
- Jasmine rice, to serve
Method
In a saucepan, bring coconut milk, stock, galangal, lemongrass and lime leaves to a gentle simmer. Do not boil it hard or the coconut can split and the aromatics turn harsh. After 5 minutes, add the chicken and mushrooms. Cook until the chicken is just done, 6–10 minutes depending on slice thickness. Add tomatoes if using. Take the pan off the heat. Season with fish sauce, lime juice, palm sugar and chillies. Taste. You want coconut and galangal first, then salt, then sour, then heat. Add lime until it lifts. Add fish sauce until it is savoury. Sugar is a pinch, not a pour.
Serve in hot bowls — heat the bowls with tap water if the kitchen is cold — with coriander, spring onion and rice. People will fish out galangal slices; that is expected. The slices have already done the work.
Notes
Prawns can replace chicken, added at the end like the Docklands tom yum, but then you are closer to tom kha goong and should not overcook them. Vegetarian: extra mushrooms, tofu, vegetable stock, and a vegetarian fish sauce. Evaporated milk is sometimes used in Australian home versions; coconut milk is the better default.
Leftover soup reheats once, gently, with a fresh squeeze of lime at the end. It does not improve if kept on the stove while someone drives in from the Western Highway. Reheat, finish, serve.
If you want a second cold-night dish, a fried paste coconut curry from the main green curry method will sit beside this soup, but split the heat: soup can be the hot column if the curry is mild. The Bendigo yellow curry is another family pot; cook it on a different night so this page still has a job.
Italian nonna recipes do not belong here. Neither do enchiladas. The URL does now.
Cold-night serving: heat the bowls. A Ballarat kitchen that pours tom kha into a cold ceramic bowl loses the first minute, which is the minute of galangal. Keep lime on the table so each person can lift their own bowl without you recooking the pot. If you want a crunch beside the soup, cucumber sticks and a pinch of salt are enough; a full som tam is a different shopping list and a different night.
Freezing: lime leaves and galangal freeze. Coconut milk does not love a freezer. Chicken leftover in the soup is a next-day lunch if you add lime again at the reheat. Do not keep adding water until it is a pale bath; eat rice with it or make a smaller pot. Goldfields shopping is weekly; this soup is daily in spirit. Buy the herbs when you are ready, not as a virtuous week-long occupant of the crisper.
