KUDUS – Rumah Makan Garang Asem Sari Rasa, or RM Gasasa, has become a go-to destination for those looking to enjoy authentic garang asem in Kudus. Located at Jalan R. Agil Kusumadya Number 20, Jati Kulon Village, Jati District, Kudus Regency, the restaurant has been in operation since 1977.
Garang asem was introduced to the RM Gasasa menu several years after the restaurant opened. The free-range chicken dish was debuted in 1986, as the family-run establishment sought to create a signature offering amid a rising number of new local eateries.
Since then, garang asem has remained a staple. The dish is served in banana leaf parcels, featuring a clear broth that balances sour, spicy, and savory flavors. Slices of green tomatoes and whole bird's eye chilies are the signature elements revealed as soon as the package is opened and the steam escapes.
The Gasasa version of garang asem uses free-range chicken as its primary ingredient. The meat is combined with green tomatoes and whole bird's eye chilies, which provide a fresh, zesty flavor and a spicy kick to the broth.
All ingredients are prepared fresh. Upon arrival, the chicken is processed, cut, and seasoned before being assembled for cooking.
RM Gasasa chef Puji Astuti emphasizes that ingredient quality is the key to the dish's flavor. Beyond the choice of free-range chicken, the freshness of the tomatoes and chilies is closely monitored before they enter the kitchen.

"It is all about the spices," said Puji. "The ingredients—tomatoes, chilies, shallots, garlic, candlenuts, and our specific spice blend—are what define the fresh and savory taste."
The spice mixture consists of shallots, garlic, candlenuts, coriander, bay leaves, and galangal. These aromatics form the foundation of the broth's depth and scent.
Notably, the spices are not sautéed beforehand. Raw free-range chicken is combined with the spice blend, green tomatoes, whole chilies, and bay leaves, then wrapped in banana leaves.
The parcels are then steamed in a large pot for approximately two hours. This slow-cooking process ensures the chicken is perfectly cooked and infused with the essence of the aromatics.
When served, the clear broth remains the highlight. The acidity comes from the green tomatoes, while the bird's eye chilies provide a heat that pairs perfectly with the savory chicken and blend of spices.
For diners who prefer a spicy kick, the whole bird's eye chilies included in the package offer an added layer of heat when enjoyed with a bowl of warm rice.
RM Gasasa offers several variations of garang asem. Guests can choose from chicken pieces, offal, or chicken feet.
The chicken and offal versions are priced at Rp 44,000 per portion, while the chicken feet version is sold for Rp 32,000. The latter is available in limited quantities, with roughly eight to 10 portions prepared daily.
These dishes are best enjoyed with warm rice and an assortment of crackers. RM Gasasa also features a variety of other options, such as traditional Kudus-style kampung chicken soto, egg and tofu rice, various mixed rice dishes, and ready-to-serve fried chicken.
For beverages, one of the signature options is Es Kopyor, priced at Rp 25,200 per glass.
Diners with specific requests regarding spice levels can coordinate with the management, provided the request is made one day in advance.
These options allow first-time visitors to customize their meals. While the chicken version is recommended for those new to the dish, the offal and feet variations cater to those looking to explore different textures.
Garang asem was not an original menu item when RM Gasasa first opened. In the early years, the founding family focused on serving a variety of common local Kudus dishes.
As the local culinary landscape in Kudus expanded, the family sought to differentiate their offerings. Consequently, garang asem was introduced and has remained a staple through to the second generation.
"From 1977 to 1986, we only served standard Kudus dishes. We introduced garang asem in 1986 because of the rise in new restaurants and competitors; we needed a unique signature dish," Yuli recalled.
With increased production, kitchen operations have evolved. Where chefs once relied on experience and intuition, recipes are now strictly measured by weight to ensure consistency in every batch.
Under normal conditions, approximately 200 free-range chickens are processed daily, a figure that rises to about 250 during peak demand. A team of 30 staff manages the operation, overseeing everything from ingredient preparation and cooking to customer service.
RM Gasasa remains at its original location. The building, initially leased, was purchased by the family in 2008 and continues to serve as the restaurant's home.
For Yuli, operational changes have not altered the traditional character of the restaurant's signature garang asem. While work methods have evolved to meet demand, the core recipe, seasoning blends, and cooking process remain strictly maintained.
Decades of operation have drawn customers beyond the local Kudus area. Among them is Almar Agustina, a diner from Semarang who visited while on a business trip with colleagues.
For Almar, RM Gasasa is a go-to spot when in Kudus. She specifically ordered the chicken garang asem for its well-balanced flavor profile.
“I’m having the garang asem. I’m from Semarang and decided to stop by. I usually make it a point to visit whenever I’m in Kudus because of its reputation,” Almar said.
She noted that the garang asem broth offers a refreshing blend of sour and spicy notes, complemented by tender chicken that absorbs the spices well.
“The taste is excellent—the perfect balance of spicy and sour. The chicken is also very tender and flavorful,” she added.
Experiences like Almar’s highlight how a signature dish can drive repeat visits. Customers return not just for the establishment's name, but for the consistent, recognizable flavor they have come to expect.
The main branch of RM Gasasa offers a spacious dining area with ample seating. Visitors can choose between the first or second floors, including air-conditioned rooms for those seeking a cooler dining environment.
The spacious layout makes this restaurant an ideal venue for family gatherings and group dining. Reservations are available for larger groups.
Beyond dine-in service, the restaurant offers takeout and pre-order options. Delivery services are also available through online platforms.
On-site parking is available for private vehicles. For groups arriving by bus or larger vehicles, dedicated parking space is also provided, with site management adjusting arrangements during peak hours.
Additional facilities include guest restrooms. For those looking to purchase souvenirs, there is a dedicated section offering local Kudus snacks, including traditional crackers and confections.
First-time visitors can refer to the menu board located in the dining area to review selections before ordering.
RM Gasasa is open daily from 7:30 a.m. WIB. Final orders are accepted until approximately 8:30 p.m. WIB, with the restaurant closing at 9:00 p.m. WIB. The lunch hour is typically busy, so diners visiting with family or large groups are advised to plan their arrival accordingly to ensure seating availability.
The main location on Jalan R. Agil Kusumadya is easily accessible from various points in the Jati area. The restaurant is situated about five minutes from GOR Djarum Jati and five minutes from Hypermart Kudus.
In addition to the flagship location, another branch in Kudus is situated on Jalan Raya Kudus-Pati, directly in front of the Kudus Police Station. Travelers visiting from out of town can also find RM Gasasa on Jalan Ki Mangunsarkoro, at the Ventura Garden Food Court in Semarang, and at 108 Jalan Parangtritis, Yogyakarta.
Originally established as a restaurant serving a variety of Kudus specialties, garang asem has become synonymous with the RM Gasasa legacy. First introduced in 1986, the dish has remained a staple through the restaurant's ongoing operational and business evolution.
The dish is traditionally served in a simple fashion: a steaming banana leaf packet is opened, releasing the aroma of the warm broth, ready to be enjoyed with free-range chicken, rice, and traditional accompaniments.
The signature flavor profile combines the acidity of tomatoes, the heat of chili, savory free-range chicken, and a delicate spice blend. This well-preserved recipe and the consistent preparation process ensure that garang asem remains an essential part of the RM Gasasa dining experience.
For visitors stopping in Kudus, a portion of garang asem offers an authentic taste of a culinary tradition that has long been a part of the city's identity. (JMY/mainkekudus)
