Kernas (Specialty Culinary of Natuna)

Kernas: A Culinary Masterpiece of Sago and Tuna from Indonesia's Northernmost Tip

Natuna Regency, situated on Indonesia's forefront, not only holds captivating underwater natural wealth but also a very specific and authentic gastronomic heritage. Among its array of local dishes, Kernas holds the highest status in the hierarchy of traditional snacks. Widely known as "Natuna Nugget," Kernas is more than just a snack; it is a symbol of food resilience, coastal cultural adaptation, and a manifestation of the rich marine produce of the Riau Islands.

Philosophy and Origin of Kernas

Kernas was born from the local wisdom of the Natuna people in processing two abundant natural resources in the region: Tuna (or simba fish) and Pearl Sago. Historically, Natuna's geographical location surrounded by the North Natuna Sea made fish its primary protein source. Meanwhile, sago has been a staple carbohydrate for the Riau Islands people long before rice became dominant.

The name "Kernas" itself refers to the texture and shape of this dish. In some villages in Natuna, this snack is also often called Luti Terasi, although the term Kernas is much more popular commercially and culturally. This dish reflects the practical lifestyle of coastal communities while still prioritizing savory and filling deliciousness.

Main Ingredients: Harmony of Sea and Land

What makes Kernas different from Palembang's pempek or other Riau Islands' otak-otak is its very specific use of ingredients.

1. Fresh Tuna: The people of Natuna are very selective in choosing fish. The tuna (Euthynnus affinis) used must be caught on the same day. The freshness of the fish determines its natural elasticity without the need for many additional chemical additives.

2. Pearl Sago (Sagu Rendang): This is the key to Kernas' authenticity. Unlike modern nuggets that use breadcrumbs, Kernas uses pearl sago that has been roasted (often called sagu rendang by locals). These sago pearls provide a coarse, crispy texture on the outside, yet soft on the inside.

3. Spice Blend: The finely ground spice mixture consists of shallots, garlic, red curly chilies for a reddish hue, along with salt and a little pepper. The use of MSG is usually minimal because the natural sweetness is derived from the fresh fish meat.

Traditional Making Process

The making of Kernas still maintains manual techniques to prevent the fish fibers from being completely destroyed. The process begins by separating the fish meat from its bones, then the meat is coarsely chopped. The fish meat is not finely ground like meatballs so that the "bite" texture of the fish meat remains dominant.

After chopping, the fish meat is mixed with the spice blend. The secret to its deliciousness lies in the ratio of fish to flour, with the fish being significantly more abundant. This mixture is then shaped into flat or oval balls. Before frying, the dough is rolled over a bed of pearl sago. This pearl sago will adhere strongly and create a protective layer that provides a unique crunchy sensation when bitten.

The frying process is done over medium heat in abundant coconut oil. Kernas is fried until it turns golden brown. The final result is a snack with a gradient of textures: crispy on the surface due to the sago pearls, and chewy-savory on the inside due to the density of the fish meat.

Legendary Culinary and Popular Destination

Although Kernas can now be found in various corners of Ranai City (the capital of Natuna), there are several spots considered guardians of the original recipe. The Pantai Piwang area and Pasar Ranai are centers where legendary Kernas artisans gather. Here, families who have passed down the Kernas recipe for three generations still use the manual sago roasting technique over wood-fired stoves to achieve a distinctive smoky aroma.

One of the unique aspects of Kernas' serving is its accompanying sauce. Kernas is never eaten alone. It is always served with a distinctive Natuna liquid chili sauce—a blend of bird's eye chilies, vinegar, and palm sugar. The sour-spicy-sweet taste of this sauce cuts through the rich, fatty flavor of the tuna, creating a perfect balance of flavors on the palate.

Cultural Context and Eating Customs

In the tradition of the Natuna people, Kernas is not just a "market food." It is a mandatory dish in small traditional ceremonies, a companion for afternoon coffee (ngopi sore), and a welcome dish for guests. There is a sense of respect when a host serves warm Kernas to guests from outside the island.

The culture of eating Kernas is also closely related to the concept of begawai (traditional feasts). Although not the main dish on a plate of rice, Kernas is often served as an appetizer that brings people together during conversations. In legendary coffee shops in Natuna, the sight of plates filled with Kernas still steaming hot, alongside a glass of black coffee, is a daily scene that depicts the peaceful life on the border.

Uniqueness of Kernas Compared to Other Cuisines

Visually, Kernas might look similar to mpek-mpek kulit or fried otak-otak, but in substance, it has a very strong character. The use of pearl sago (not fine sago flour) gives it a coarse, speckled visual identity, which is not found in other regional cuisines in Indonesia.

Furthermore, Kernas reflects food independence. While other regions rely on imported wheat flour to make fried snacks or nuggets, the people of Natuna remain loyal to local sago. This makes Kernas one of the most sustainable and environmentally friendly culinary items, as all its ingredients are sourced within a radius of just a few kilometers from the processing location.

Preservation Efforts and Future

Currently, Kernas has begun to transform. Some local entrepreneurs are starting to package Kernas in the form of frozen food so it can be taken as souvenirs to Batam, Tanjungpinang, and even Jakarta. However, culinary maestros in Natuna still believe that the best way to enjoy Kernas is directly on the shores of Natuna, right after it's taken out of the frying pan.

The Riau Islands regional government also continues to encourage Kernas to gain recognition as Intangible Cultural Heritage (WBTb). This is important not only for the protection of culinary intellectual property rights but also as a form of appreciation for the coastal women of Natuna who have kept this recipe alive in their kitchens for decades.

Conclusion: Why You Should Taste Kernas?

Consuming Kernas is the best way to "taste" the sea of Natuna. In every bite, there is a trace of the North Natuna Sea waves, the aroma of the land where sago grows, and the warmth of the hands of Natuna mothers who meticulously blend the spices. Kernas is proof that the simplicity of ingredients, when processed with the right techniques and passed down with love, can become a legendary culinary masterpiece. If you visit Natuna, missing Kernas is like missing half of the island's soul.
