Ingredients (serves 1–2)
- 300 g prawns (peeled and deveined)
- 2 large tomatoes, chopped
- 1 onion, finely chopped
- 3 garlic cloves, chopped
- 1 piece of ginger, grated
- 2 tablespoons tomato ketchup
- 1 teaspoon chilli powder (to taste)
- 2 tablespoons oil, for frying
- Salt and pepper, to taste
- Fresh coriander leaves, to garnish
Shopping for the ingredients
To make Udang Masak Merah, it pays to shop for the ingredients carefully in advance. Visit an Asian supermarket or a well-stocked grocer to find fresh prawns and authentic spices. Fresh tomatoes are especially important, as they give the dish its natural sweetness. Make sure the spices — particularly the chilli powder — are of good quality, so you capture the true taste of Malaysia.
Preparing the dish
Good preparation is the first step towards a successful Udang Masak Merah. Begin by cleaning the prawns and patting them thoroughly dry. Chop the onion, garlic and tomatoes ahead of time to speed things up at the stove. Cutting the ingredients properly ensures they cook evenly and lets the flavours develop to their full potential.
Step-by-step instructions
- Heat the oil in a pan, add the chopped onion and fry until golden brown.
- Add the chopped garlic and grated ginger and fry briefly until fragrant.
- Tip the chopped tomatoes into the pan and let them soften, stirring constantly.
- Add the ketchup, chilli powder, salt and pepper, and let the sauce simmer for a few minutes.
- Add the prawns and cook them in the sauce until they are tender and pink.
- Serve the dish hot, garnished with fresh coriander leaves.
Gluten-free / lactose-free version
Udang Masak Merah is naturally gluten-free and lactose-free, provided you take care with your ingredient choices. Use a gluten-free ketchup, or replace it with fresh tomatoes and a little honey for sweetness. No special measures are needed for lactose-free cooking, as the dish contains no dairy products by nature. That means people with specific dietary needs can enjoy the flavours of this delicious dish too.
Tips for vegans and vegetarians
Udang Masak Merah also offers plenty of scope for vegans and vegetarians. Replace the prawns with tofu or tempeh to achieve a similarly satisfying result — the same plant-based pairing that stars in Tahu Tempe. Adjust the spices and the sauce accordingly to let the natural character of the plant-based ingredients shine. This way, plant-based eaters can savour this fantastic dish without missing out on any of the flavour.
More tips and tricks
To make your Udang Masak Merah even more aromatic, try adding extra spices such as turmeric or cumin. Simmer the sauce a little longer so the flavours can develop more intensely. A squeeze of lime juice at the end of cooking gives the dish a fresh lift. And do not forget: the prawns should not be cooked for too long, or they will turn tough.
Adapting the recipe to your taste
Udang Masak Merah is a versatile dish that is easy to adapt to personal preference. Vary the heat to suit your taste by using more or less chilli. You can also enrich the sauce with coconut milk for a creamier consistency — a trick beloved in dishes like Laksa. Be creative and experiment with different vegetables or sources of protein.
Ingredient substitutions
There are plenty of sensible alternatives you can use for Udang Masak Merah. Instead of fresh prawns, frozen prawns or other seafood — think of the squid in Sambal Sotong — work well too. If tomatoes are not available, tomato purée or passata makes a good stand-in. The dish stays simple and delicious even when you do not have every ingredient to hand.
Drink pairing ideas
A few well-chosen drinks round off the Udang Masak Merah experience nicely. A light, refreshing beer pairs perfectly with the dish’s spicy flavours. A glass of chilled brewed tea or a sweet mango juice complements the aromas beautifully as well. Experiment with both alcoholic and alcohol-free options to find your perfect combination.
Serving and presentation ideas
Presentation can greatly enhance the enjoyment of Udang Masak Merah. Serve the dish in attractive bowls and garnish it with fresh coriander leaves and lime wedges. A few slices of red chilli make a handsome decoration too. Be sure to serve the dish on warmed plates to preserve both temperature and flavour.
