In the kitchen, bruise lemongrass with the back of a knife and the green citrus aroma rises first. Fry a yellow paste of turmeric, galangal and chili in oil, and even before the fish goes in, you feel a little closer to a Sumatran table. Arsik is a dish that moves that aroma slowly into the fish.
Arsik (Arsik / ᯀᯒᯘᯂ) is a Batak dish from North Sumatra, Indonesia. Locally it is often made with ikan mas, a carp-family fish, and is known as a dish that comes up at wedding and ceremonial tables. Outside Indonesia, fillets of sea bream, cod, Spanish mackerel or yellowtail, sold for cooking, are easy to handle. What matters is less matching the fish exactly than not scorching the yellow aromatic paste, not moving the fish too much, and letting the acidity simmer round.
Search for arsik and you often find only an explanation of the name. But what actually trips you up in the kitchen are the days you have no andaliman, the days you can't get a souring ingredient like asam cikala, and the days the fish seems about to fall apart. This article keeps the axis of North Sumatran aroma and recasts it in a form you can make from ordinary shopping.
What Is Arsik?
Arsik is fish braised in a yellow bumbu (aromatic paste). The color of turmeric, the aroma of lemongrass and galangal, the acidity of tamarind or citrus, and the heat of chili layer on each other. It is easier to make if you think of it not as a dish weighed down with coconut milk but one where the fish flesh absorbs the aromatic sauce and rice catches it.
A feature often cited in Batak cooking is andaliman. A spice with a numbing quality close to sansho pepper and a citrus-like aroma, it defines the impression of North Sumatran food. Not many shops keep it on hand, though. It is not a perfect substitute, but a small amount of Sichuan peppercorn can move the numbness and aroma in that direction. Too much pulls it toward Chinese cooking, so start with 1/4 tsp for 4 servings.
Another local mark is acidity. Local recipes name souring ingredients of the region such as asam cikala and asam gelugur. Outside Indonesia, a small amount of tamarind paste with lime added at the end to supplement the aroma gives not just sourness but a braising liquid whose sweetness and the fat of the fish come together.
| Local axis | Role | Realistic approximation |
|---|---|---|
| ikan mas | Freshwater fish umami and bone-in stock | Fillets of sea bream, cod, Spanish mackerel or yellowtail. Closer if bone-in |
| andaliman | Citrus-like numbness | Just 1/4 tsp Sichuan peppercorn. Don't overdo it |
| asam cikala | Round acidity | Supplement with 2 tsp tamarind paste and lime juice |
| galangal | Harder, cooler than ginger | Thin slices of frozen galangal. If none, just a little ginger |
| daun jeruk | Aroma of citrus leaf | Frozen makrut lime leaves. If none, a little lime zest |
Ingredients (serves 4)
Skin-on fillets are easiest to handle. Mixing in a few bone-in fish collars makes the broth deeper, but for the first time fillets that don't fall apart are enough.
Allergens and heat
This is a fish dish. If you are concerned about nuts, omit the candlenuts or macadamia nuts and add 1 tsp oil to the aromatic paste to help it hold together. It works without the chili, but increasing the Sichuan peppercorn to make up for heat shifts the aroma, so it is better to let only those who want heat add sambal in their own bowl.
Ingredients That Cause Hesitation When Shopping
What is worth seeking out specially is not the fish but the aroma and acidity. Buy the fish at a nearby fish counter and gather galangal, lemongrass, makrut lime leaves and tamarind in small quantities, and they carry over to your next papeda (in Japanese) or tom kha gai (in Japanese).
| Ingredient | Priority | Reason |
|---|---|---|
| Galangal | High | Ginger alone struggles to give North Sumatra's hard citrus feel |
| Lemongrass | High | Rounds the fish smell and lightens the yellow sauce |
| Makrut lime leaves | Medium | Gives the braising liquid a citrus outline. Frozen is convenient |
| Tamarind | Medium | Easy to make a round acidity close to the local souring ingredients |
You don't need to get everything in large bags from the start. For arsik alone, prioritize galangal, lemongrass and tamarind, and add makrut lime leaves if you spot a small frozen bag. Souring with lime alone gets too light, so look for a small jar of tamarind at an import store or an Asian grocery online and flavor adjustment gets much easier. The useful extras are aromatic ingredients easy to move to other dishes after leftovers, Sichuan peppercorn as the andaliman substitute, and sambal to split the heat at the table.
On days you can't find andaliman, a small amount of Sichuan peppercorn moves the numbness in that direction. Buy it whole and crush coarsely just before using, and it keeps a more citrus-like aroma than powder.
Frozen makrut lime leaves have a strong aroma in a small amount, and the rest is easy to move to curries and soups. For people who want a citrus outline in the braising liquid, they are worth looking for after lemongrass.
On days you want to divide the heat within the family, serving sambal in a separate dish is easier than putting too much chili in the pot. Leftover sambal also goes into nasi goreng, sate and egg dishes.

Method: Don't Move the Fish, Simmer in the Aromatic Sauce
Arsik is not a dish to boil hard and flake the fish. Fry the aromatic paste first, then lay the fish in gently at a heat where the surface of the liquid just trembles with bubbles. Spooning the liquid over rather than flipping keeps the flesh from breaking and concentrates only the sauce.
The easiest failure with arsik is not weak flavor but the fish breaking apart. It is fine if the liquid only half covers it. Spoon the liquid over instead of flipping, and keep the heat between medium-low and low. A hard boil splits the flesh and clouds the sauce.
What to Keep and What You Can Change Outside Indonesia
When making arsik in your own kitchen, separating the axes of the dish fails less often than trying to gather every local ingredient. What to keep is the yellow aroma, the round acidity, the lingering numbness, and heating without moving the fish.
| Decision | What to keep | What you can substitute |
|---|---|---|
| Aroma | Any two or more of lemongrass, galangal, citrus leaf | Without makrut lime leaves, a little lime zest |
| Color | The yellow of turmeric | Powder is fine if no fresh |
| Acidity | The round acidity of tamarind | On days with lime only, add 1/2 tsp sugar |
| Numbness | The direction of andaliman | A little Sichuan peppercorn. Don't add much |
| Fish | Thick fillets | Sea bream, cod, Spanish mackerel, yellowtail, swordfish |
On days without galangal, adding a lot of ginger inevitably pulls it toward an ordinary ginger-simmered fish. If you make it with ginger, increase the lemongrass and makrut lime leaves and keep the ginger to 10 g. On days without tamarind, mix 1 tbsp lime juice, 1/2 tsp dark brown sugar and 1 tbsp water, but the reduction is lighter, so allow a longer rest at the end.
Where It Tends to Go Wrong
| Symptom | Cause | Fix |
|---|---|---|
| Fish broke apart | Boiled hard, flipped midway | Next time use medium-low. This time move the large pieces to the plate and spoon sauce over |
| Floury taste | Paste not fried long enough | Return only the sauce to the pot and reduce 3 minutes over low heat |
| Too sour | Too much tamarind and lime | Add 1/2 tsp raw cane sugar and 2 tbsp water and warm 2 minutes over low heat |
| Weak aroma | Herbs only boiled from cold water | Add 1/2 stalk lemongrass and 1 makrut lime leaf and warm 3 minutes over low heat |
| Fishy | Moisture left from prep | Add 1 tsp lime juice at the end and increase the herbs a little |
Underreduction is obvious the moment you plate it. If the sauce runs off the fish and spreads like water to the edge of the plate, it is too early. Take out the fish first, reduce only the sauce 2 to 3 minutes over low heat until a spatula's track is visible, then return the fish.
Storage and Making Ahead
Arsik lets the aroma enter the fish better after sitting about 20 minutes than when freshly made. But since it is a fish dish, avoid leaving it long at room temperature.
| Method | Guide | Reheating |
|---|---|---|
| Refrigerate | 2 days | In a pot, add 2 tbsp water and heat 5 minutes over low heat |
| Freeze | Not suitable | The flesh breaks easily and the herbs' aroma fades |
| Make ahead | Sauce only the day before | Fry the paste and make the braising liquid, add the fish on the day |
After refrigeration the sauce firms up. Microwaving alone tends to harden the edges of the fish, so use a small pot over low heat if you can. Warm it spooning sauce over the top without touching the fish, and the flesh breaks less.
Building a Menu Around It
Arsik is a rich fish dish that suits rice. Keep side dishes from being too oily and cut with vegetables or acidity to make it easier to eat.
| Dish to pair | Reason |
|---|---|
| Papeda (in Japanese) | Lets you compare the same Indonesian line of fish and yellow aromatics |
| Pindang (in Japanese) | A South Sumatran sour soup that lets you eat fish lightly with tamarind and herbs |
| Gado-gado (in Japanese) | Warm vegetables with peanut sauce round out the table |
| Ayam betutu | Easy to compare as a Balinese dish that also uses aromatic paste |
| Tom kha gai (in Japanese) | Uses up leftover galangal, lemongrass and makrut lime leaves |
Cooking dishes that share the same herbs in a row lowers the psychological hurdle of shopping. Frozen lemongrass goes to soups, makrut lime leaves to curries, and tamarind to pad thai (in Japanese).
FAQ
Q1. Is it not arsik unless I use carp?
Ikan mas is often used locally, but at home you can prioritize availability and ease of handling. You can make it with thick fillets such as sea bream, cod, Spanish mackerel or yellowtail. Bone-in fish makes the broth deeper, but for the first time, fillets that resist breaking are safer.
Q2. I can't get andaliman.
You can make it without it. To approach the aroma, use just 1/4 tsp Sichuan peppercorn. Increasing the amount pulls it toward Chinese mala, so the trick is not to make the numbness the star.
Q3. Can I make it without tamarind?
You can. Substitute a mix of 1 tbsp lime juice, 1/2 tsp dark brown sugar and 1 tbsp water. It will not have the round acidity of tamarind, so hold back a little on the finishing lime and taste before adding.
Q4. Can I make a mild arsik for children?
Yes. Leave out the red chili and the Sichuan peppercorn. The axis of aroma remains in turmeric, lemongrass, galangal and makrut lime leaves, so even without heat it stands as a yellow aromatic fish braise. Serving sambal only in the adults' bowls lets you adjust at the table.
Q5. What do I do if the fishy smell bothers me?
Leave it 10 minutes with salt and lime and be sure to wipe off the moisture that comes out. Boiling hard after adding to the liquid brings out the fishy smell, so keep the simmer just bubbling over medium-low heat. Add the finishing lime juice after turning off the heat to keep the aroma.
