Rumah Bumbu A Taste of Kalimantan Elegantly Rooted in Sabah’s Culinary Scene - feature by Writer On-The-Go Lorena Binisol

In the ever-evolving landscape of Sabah’s dining culture, where modern cafés and fusion kitchens continue to bloom across the city, one humble establishment is quietly capturing hearts through authenticity, heritage, and the soulful language of spices. Tucked within the growing culinary conversation of Kota Kinabalu, Rumah Bumbu arrives not merely as a restaurant, but as a deeply personal narrative plated with memory and tradition.

Cikgu Kath, the head chef of Rumah Bumbu

Founded by Beatrice Peter, affectionately known as @CikguKath, Rumah Bumbu is a tribute to her Kalimantan roots and to the woman who shaped her understanding of food, her mother, Yuliana Balang Pangiran. Barely two months after opening its doors on March 16, the restaurant has already begun building a loyal following among diners seeking flavours that feel sincere, comforting, and beautifully unfamiliar.

At Rumah Bumbu, recipes are not manufactured for trends. They are inherited.

The kitchen moves with patience and purpose. Spice pastes are blended fresh daily, broths simmer for hours, and every preparation reflects an old-world philosophy where cooking is treated as devotion rather than convenience. No instant powders. No shortcuts. Only layers of flavors built slowly, intentionally, and respectfully.

Sup Konro the signature dish

The restaurant’s signature creation, Sup Konro, stands proudly at the center of its identity. The rich and aromatic beef soup first gained attention during the KDCA Kaamatan Festival several years ago, where Kath introduced the dish to the Sabah public for the very first time. Encouraged by her brother, the owner of Barbarian Re-born, she transformed a treasured family recipe into a culinary experience now sought after by many.

What makes the dish remarkable is not simply its flavors, but its emotional depth. Every bowl carries echoes of family gatherings, festive celebrations, and the warmth of Kalimantan hospitality. Tender beef, deeply infused broth, and fragrant spices come together in a composition that feels both bold and nostalgic.

Equally memorable is Rumah Bumbu’s sambal, a fiery accompaniment adored by returning guests. Intensely aromatic with layers of chilli, herbs, and traditional spices, the sambal delivers the kind of lingering heat that keeps conversations alive long after the final spoonful.

Another cultural essential arrives in the form of kerupuk, the beloved Indonesian crackers served alongside many dishes. At Rumah Bumbu, kerupuk is not treated as a garnish, but as an integral part of the dining ritual itself, reflecting the celebratory spirit commonly found in Indonesian households.

The name Rumah Bumbu, translated as “House of Spices,” perfectly encapsulates the restaurant’s philosophy. Turmeric, galangal, ginger, chillies, and fragrant herbs become more than ingredients here. They become storytellers. Each dish unfolds like a journey through the vibrant culinary heritage of Kalimantan, interpreted with care and served with heartfelt sincerity.
