Seblak: West Java's Chewy, Spicy Kerupuk Soup

When kerupuk loosens in the pot, the kitchen moves toward a West Java street stall

Some evenings you want something warm, but not ramen or hot pot. You soak kerupuk, the dried cracker like a shrimp chip, in water, and fry an aromatic paste of crushed red chili, shallot, garlic and kencur in oil. Pour in the water, and an earthy, quick-passing aroma rises in the kitchen. It is a heat with a root aroma, a little different from Japanese chili dishes.

Seblak is a spicy kerupuk stew loved in West Java, Indonesia, especially around Bandung. The star is dried, unfried kerupuk soaked in water until chewy and then simmered in an aromatic broth. Some stalls add egg, greens, macaroni, meatballs, chicken feet, sausage or seafood, but the core of the taste is "the soaked kerupuk," "kencur" and "chili."

The hard part of making it elsewhere is less the ingredient names than the texture. Soak the kerupuk too long and it tears in the pot and turns slimy. Soak it too little and a hard core remains in the center. This article is a home version in which the kerupuk soaks 20 minutes and then simmers briefly. If you don't have kencur, bring the aroma close with frozen galangal and ginger and adjust the heat with sambal.

If you keep cooking Indonesian food, it connects with mie goreng, which uses the same sweet-salty seasoning, the skewered sate ayam and the vegetable gado-gado. Within these, seblak is the slightly unusual plate that eats kerupuk like a staple.

What seblak is | The idea of eating kerupuk chewy, "not fried"

Kerupuk is a cracker served at tables and stalls in Indonesia. Most are fried and eaten crisp, but in seblak raw dried kerupuk is soaked in water and simmered in a spicy aromatic broth. This idea of "deliberately making chewy what was meant to be crisp" is the interest of seblak.

In local explanations, seblak is often introduced as a West Javanese dish that began in Bandung, and in recent years the ingredients have multiplied at stalls, eateries and on social media. While it can include macaroni, egg, greens, meatballs, seafood and even chicken feet, to move closer to the older form it matters not to blur the aroma of kerupuk and kencur.

Hearing the name you might think it is only about heat, but eating it, the impression is much softer. Kerupuk is not as heavy as starch noodles or rice cake, and bounces a little when it holds the broth. With the softness of egg and the greenness of leafy vegetables added, your chopsticks keep moving despite the heat.

Ingredients (serves 3) | First decide the kerupuk and the aromatic roots

This makes three servings. Kerupuk swells in the pot, so it eats more substantially than its dried amount suggests. If someone dislikes heat, halve the red chili and add the sambal at the table, not in the pot.

Notes on allergies and heat

Some kerupuk products contain shrimp, fish, wheat and egg. If you have a shrimp allergy, check the ingredient labels and avoid shrimp kerupuk and frozen shrimp. If leaving out the egg, adding 80 g thick fried tofu makes up the protein and substance.

It is safer to add heat later with sambal than with chili. The first time, keep to 3 red chilies and 1 tbsp sambal, and add more at the table.

Substitutes | When there is no kencur, what to protect

The ingredient that troubles shoppers most for seblak is kencur. It is a root smaller than the galangal seen in Thai cooking, more medicinal than ginger, with a strong earthy aroma. Without it you can't get exactly the same aroma, but using a little each of frozen galangal and ginger keeps it from being merely a chili soup.

The substitute for kerupuk is also a puzzle. Store-bought fried shrimp chips don't give the chewiness characteristic of seblak. If you really have no dried kerupuk, there is a method of breaking dried rice paper into 3 cm squares and simmering 30 seconds, but it comes close to a different dish. If possible, use dried kerupuk.

Shopping guide | Look only at the core of the flavor, not ordinary eggs or greens

Seblak is not a dish where you search out eggs or greens specially. What is worth buying are the kerupuk that is hard to find in a nearby supermarket, the aromatic root to approximate kencur, the sambal that builds the outline of the heat, and the kecap manis you can use to adjust sweet-and-salty.

Kerupuk is the star of this dish. Look not for fried shrimp chips but for the dried type that can be soaked and simmered, and you get closer to the chewy texture characteristic of seblak.

When you can't find kencur, using a little frozen galangal helps you avoid the flat heat of chili and garlic alone. A root aroma stays deeper than when you make it with ginger alone.

If you settle the heat in the pot, it is hard to divide in a family. With sambal on hand, you keep it modest in the pot and only those who like heat add it at their plates.

Kecap manis is not an essential ingredient of seblak, but 2 tsp adds a sweet roundness to the spicy broth. Leftover goes easily to nasi goreng, mie goreng and sate ayam, so it is a seasoning easy to use up for people who keep cooking Indonesian food.

Instructions | Soak the kerupuk and simmer it briefly

Seblak looks like a spicy soup, but the cause of failure is water management more than heat. Soaking the kerupuk too long, under-frying the aromatic paste, and simmering the ingredients too long after adding them: these three make the aroma blur and the texture heavy.

How to eat | Adjust the heat at the edge of the plate

Seblak is best freshly made. Because the kerupuk keeps absorbing the broth, leaving it long after serving takes it past chewy into heavy. Once you've put it in bowls, eat the first few bites as they are, and then mix in the sambal a little at a time and the flavor won't be monotonous.

Light accompaniments suit it: cucumber, tomato, lemon, fried shallots, and extra fried kerupuk. Rather than serving it with rice, it is better as a light meal on a different day from nasi goreng (in Japanese) or mie goreng.

If someone in the family wants less heat, put only 1 tsp of sambal in the pot and the rest in small dishes. People who like heat can mix sambal and lemon at the edge of the plate and coat the kerupuk bit by bit, so the aroma doesn't flag to the end.

Where it tends to go wrong | Soggy, too hot, thin aroma

Seblak is a dish where ingredients are easy to add, but putting everything in from the start makes it unclear what you are eating. For the first time, kerupuk, egg, greens and a little shrimp or meatballs are enough. Once you're used to it, add fish balls, chicken balls, glass noodles, napa cabbage and mushrooms.

Storing and making ahead | If you keep it, separate the broth and kerupuk

Seblak is not suited to making ahead. Because the kerupuk keeps absorbing the broth, left overnight in the refrigerator it moves from chewy to a sticky stew.

If you want to make it ahead, make only the aromatic broth and store the kerupuk dried, unsoaked. Just before eating, soak the kerupuk 20 minutes and simmer it 5–6 minutes in the warmed broth, and it comes close to fresh.

If you store leftover seblak, let the heat go off, put it in an airtight container and eat it by the next day, refrigerated. To reheat, move it to a pot, add 80 ml water and warm 3–4 minutes over medium-low heat. In a microwave, warm at 600 W for 2 minutes, stir once and warm 1 more minute. Either way, boiling hard breaks the kerupuk.

The ingredients you buy for seblak can be used in other Indonesian articles. If you bought kecap manis, mie goreng and sate ayam, which use its sweet char aroma, are easy to make next. If you want to use up the sambal, sorting out how to place heat with how to make a sambal substitute makes it easier to separate what is stir-fried in from what is served on the side.

For a vegetable-centered table, go to gado-gado; for a rich stew, to rendang (in Japanese); to know the aroma of a black soup, to rawon (in Japanese). Seblak is closer to a light meal than these dishes, and differs in making kerupuk the star.

Even among "spicy soups," Thai tom yum leans on herbs and sourness, and Korean jjigae on fermentation and chili powder. Seblak's axis is the root aroma of kencur and the texture of soaked kerupuk. If you protect that, even a home kitchen makes more than a merely fiery soup, and keeps its West Javanese character.

FAQ | Where people get stuck making seblak

Q1. Can I make it without kencur?

You can. But the aroma changes quite a lot. If you have no kencur, use 8 g frozen galangal and 5 g ginger together. Increasing only the ginger moves it toward a plain ginger soup.

Q2. Can I substitute store-bought fried shrimp chips?

I don't recommend it. Fried shrimp chips tend to crumble on the surface when simmered, and it is hard to get the chewy texture of seblak. If you really use them, don't simmer them in the pot; set them on the bowl at the end.

Q3. Can I make seblak that isn't spicy?

With 1 red chili and 1 tsp sambal it is much milder. Leave the kencur, shallot and garlic in the aromatic paste and reduce only the heat. If you took out too much heat, 1 tsp kecap manis and a little lemon can restore the outline.

Q4. What can I add to make it more local?

Meatballs, fish balls, chicken feet, sausage, glass noodles, macaroni and greens go well. But in a home kitchen, putting in everything from the first time makes the broth thin. It fails less if you first make it with egg, greens, macaroni and a little shrimp, and add ingredients the next time.

Q5. Can I make it as next-day lunch?

It isn't suited to a lunch box, since it has broth and heat and the kerupuk breaks down over time. If you eat it the next day, refrigerate it and reheat it in a pot with water added. If you make it ahead, the realistic way is to make just the aromatic broth first.

Summary | Chewy kerupuk and the root aroma, more than the heat

Seblak is not a dish that is finished by adding more chili. The chewy texture of soaked kerupuk, the earthy aroma of kencur, a red broth rounded a little by egg: when these three come together, it stands up not as a merely spicy soup but as a West Java street dish.

If you make it elsewhere, first gather dried kerupuk and sambal. If you can't find kencur, bring it close with frozen galangal and ginger. Soak the kerupuk 20 minutes and keep it within 6 minutes in the pot. Fry the aromatic paste until red oil appears, and add the egg softly over low heat. Keep to this order and the chewy heat characteristic of seblak appears at the moment the kerupuk loosens in your kitchen.

To widen Indonesian cooking next, go on to mie goreng, which uses the same seasoning, sate ayam, the sweet soy skewers, and gado-gado, the vegetables with peanut sauce, and you can use up what you bought without strain.
