How to make Goan prawn xac xac with sun-dried spices
Goan prawn xac xac is a deeply aromatic, gently sour dry curry from Goa’s food culture. Prawns are cooked with coconut, chilli, tamarind and kokum until the sauce clings to them instead of pooling around them. The concentrated seasoning makes it especially good with plain rice, while sun-dried spices add a deeper, rounded fragrance.
Traditional versions rely on a fragrant, sun-dried masala rather than a blunt commercial curry powder. Goan Flavour’s small-batch masalas and curry preparations are made with locally sourced ingredients and supervised by experienced cooks, while a home-ground blend brings that same emphasis on freshness to the recipe. Coriander, cumin, fenugreek, pepper and dried chilli form the aromatic backbone.
For an Australian kitchen, start with fresh green prawns, good tamarind and real kokum. Those ingredients are easy to find at specialist Asian grocers in Melbourne, Sydney, Adelaide and Brisbane, while any reputable fishmonger can supply the prawns. The recipe below serves four and uses metric measurements, so it scales cleanly for a family lunch or a relaxed Sunday cook.
Make the sun-dried masala
For a small batch of goda-style masala, measure 2 tablespoons coriander seeds, 1 tablespoon cumin seeds, 2 teaspoons fenugreek seeds, 1 teaspoon black peppercorns, 10 grams dried red chillies and ½ teaspoon turmeric. The quantities matter because xac xac should build fragrance in layers without tasting heavily spiced. Choose dried chillies that smell sweet and earthy rather than dusty or scorched.
Toast the coriander, cumin, fenugreek and peppercorns in a dry pan over low heat for 2–3 minutes, shaking often, until fragrant but not brown. Add the chilli and turmeric for the final minute. Cool the mixture completely, then grind it in a spice grinder to a coarse powder. Coarse grinding preserves a little texture and releases more aroma during cooking.
Traditional cooks dry fresh chillies, coriander and aromatic roots in the sun before grinding them. Australia’s sun is powerful, but humid coastal weather can slow outdoor drying, so a dehydrator set around 70°C gives a more even result. Dry ingredients must become completely brittle before grinding; trapped moisture can make the masala dull and encourage mould. Store it airtight, away from a hot kitchen benchtop, and use it within a few months.
Prepare the prawns and sour seasoning
At an Australian fish counter, “green prawns” normally means raw, shell-on prawns, not a special green-farmed variety. Ask for 700 grams shell-on and have them peeled and deveined, or buy about 500 grams cleaned prawns. Sydney’s Fish Market, the fish counters at Melbourne’s Queen Victoria Market and Adelaide Central Market are useful places to compare fresh batches and prices.
Pull off any remaining tails, check each prawn for the dark vein and pat the flesh thoroughly dry. Large prawns can be halved for even cooking, while small ones should stay whole. Salt them only when they enter the pan; salting too early can make their surface wet and hinder the brief sear that gives xac xac its lightly charred flavour.
For the sourness, soften 1 tablespoon tamarind paste with 2 tablespoons water, then add ¼ teaspoon kokum paste. If using concentrated tamarind rather than ready-to-use paste, check its strength and start with ½ teaspoon. Indian grocery shops in suburbs such as Footscray, Parramatta and Adelaide’s CBD commonly stock both, often as blocks or frozen pellets. Fresh kokum petals are worth seeking, but consistent quantities of paste make the dish easier to reproduce.
Cook the curry without overworking the prawns
Heat 2 tablespoons coconut oil in a wok or heavy saucepan over medium-high heat. Add 1 finely chopped medium onion and cook for 6–8 minutes until soft and golden at the edges. Add 4 crushed garlic cloves, 20 grams grated ginger and 1 sliced green chilli, stirring until the raw smell disappears.
Stir in 1½ tablespoons of the ground masala and cook for 30–45 seconds, allowing the spices to toast in the oil. Add 2 tablespoons grated fresh coconut, 100 millilitres of full-fat coconut milk, the diluted tamarind and kokum, and ½ teaspoon salt. Bring the mixture just to a simmer so it smells fragrant without scorching.
Turn the heat to medium, add the prawns in one layer and cook for 90 seconds without moving them. Turn once, then cover and cook for another 2–3 minutes, until the prawns are opaque and just firm. Uncover and simmer for 2–4 minutes until the liquid becomes a glossy glaze that coats the prawns. Taste for salt and avoid a hard boil, which turns seafood rubbery.
Adjust for Australian produce and brands
Australian supermarkets usually sell long green chillies, which are mild enough for the quantity given here. Bird’s-eye chillies are hotter and smaller, so halve them or remove the seeds. Fresh coriander comes in large bunches; chop the leaves for a bright finish, but add them after the heat is off so their flavour stays aromatic rather than cooked away.
Coconut milk generally comes in 400-millilitre cans, so a little goes a long way in this recipe. Use full-fat milk for body and shake the can before pouring, since separation is common and does not affect the dish. Fresh coconut is sold grated in plastic tubs in many shops, yet a whole kernel grated at home has a cleaner flavour and a pleasant texture against the prawns.
When a full sun-dried masala is not practical, a spice powder from Goan Flavour can provide the seasoning base. The home-ground blend still contributes toasted coriander and fresh fenugreek bitterness that many ready blends soften. Keep the portions modest and taste before adding more, especially when the chosen masala already contains chilli, coconut, tamarind or salt.
Serve and store it the right way
Serve the xac xac straight from the pan with steamed medium-grain rice, the way it is commonly eaten along Goa’s coast. Spoon the prawns and concentrated sauce over the rice rather than adding a large ladle of gravy. Coriander leaves and a final pinch of grated coconut make a fresh finish. A small squeeze of lime may be added at the table, though kokum supplies a gentler sourness.
Keep leftovers in an airtight container in the refrigerator and eat within two days, although the prawns are at their best on the day they are cooked. Reheat gently in a pan with a spoonful of water, adding just enough to loosen the glaze, and avoid microwaving on full power. Properly made, the dish is fragrant, gently sour and lightly spicy, with tender prawns and concentrated flavour rather than heavy gravy.
