What is Asin Ikan Mas?

Asin Ikan Mas is an Indonesian carp dish in which fish is gently cooked in a seasoned, sour sauce. Its flavours come from tamarind, lemongrass and a freshly ground blend of aromatics.

This version keeps the cooking method straightforward: the sauce comes to a boil first, then the carp simmers in it until done. That gives the fish time to take on the sauce without requiring a separate frying step.

Nutrition and macros by portion

The nutrition label shows one serving as written: 1750 calories, 0g protein, 0g carbs, 0g fat.

The carp provides most of the protein, while the shallots and other aromatics contribute some carbohydrate. Candlenuts are the main source of fat in the sauce; serve the fish with a moderate portion of rice and vegetables to balance the plate.

The aromatic paste

Spice paste: grind the candlenuts, shallots, garlic, ginger, turmeric and galangal together until well combined. A fairly smooth paste disperses more evenly through the cooking liquid.

Lemongrass: crush the stalks before adding them to help release their fragrance. They flavour the sauce as it simmers.

Getting the tamarind sauce ready

Tamarind water: mix the tamarind with the measured water before it goes into the wok. This gives the sour ingredient a chance to spread through the liquid.

Bring the sauce to a boil with the paste and lemongrass before adding the carp. Once the fish is in, lower the heat so the sauce simmers rather than bubbles hard.

How to tell when the fish is cooked

Timing: allow the carp to simmer gently for 20 minutes, as directed. The precise cooking time can depend on the thickness of the pieces, so check the thickest part.

Doneness: the flesh should be opaque and separate easily when tested with a fork. Handle the fish gently while it cooks to help keep the pieces intact.

Seasoning the carp

Salt and pepper: rub these over the fish before cooking so the seasoning is in place before it enters the sauce. Salt is listed as to taste because the recipe does not give a quantity.

The tamarind brings the main sour note, while the aromatics provide depth. Taste the sauce carefully near the end and adjust its seasoning if needed.

What to serve with it

Rice is a practical accompaniment, soaking up the tamarind sauce and making the meal more substantial. Serve the carp and sauce together so each portion gets some of both.

For a more rounded plate, add a simple vegetable side, such as steamed greens. Keep its seasoning fairly restrained so it does not compete with the fragrant sauce.

Recipe notes & tips

• Crush the lemongrass stalks before adding them to the wok.
• Grind the paste ingredients thoroughly so they blend into the sauce.
• Keep the heat low after adding the carp to maintain a gentle simmer.
• Use a wide wok or pan so the fish can sit in the sauce without being crowded.
• Check the thickest piece for doneness after 20 minutes.

Variations

• Adjust the heat: add a fresh chilli to the paste if you would like a hotter sauce.
• Use fish portions: cut the carp into evenly sized pieces to help them cook at a similar rate.
• Add vegetables: serve with steamed greens on the side for freshness.
• Make the paste ahead: grind the aromatics shortly before cooking and keep the paste covered until needed.

Common mistakes to avoid

• Boiling too fiercely: the fish can break apart; reduce the heat to a gentle simmer after adding it.
• Adding the fish too early: wait until the tamarind water and paste start to boil.
• Leaving the paste coarse: grind it well so its ingredients are distributed through the sauce.
• Guessing doneness from time alone: check the thickest part and look for opaque flesh that separates easily.
• Forgetting to season the carp: rub it with salt and pepper before cooking.

How to store

Refrigerate leftovers in a covered container and eat within 2 days. Reheat gently in a pan until piping hot, taking care not to break up the fish.
