Teochew Slice Mackerel Fish Soup
Fortune Centre, 190 Middle Road, #02-31, Singapore 188979
Overview
There is a particular kind of culinary courage in Singapore’s hawker landscape — the courage of an eatery that refuses to be what its signage suggests. Diner’s Shack, nestled on the second floor of Fortune Centre along Middle Road, announces itself with the aesthetic vocabulary of an American roadside diner: chrome-bright in spirit, casual in posture. And yet, the dish that has made its name ring across the island is resolutely, beautifully Teochew. The Slice Mackerel Fish Soup at $5.50 is a study in restraint and generosity in equal measure — and in a food culture increasingly afflicted by shrinkflation and corner-cutting, this bowl stands as something of a quiet act of defiance.
Ambience & Setting
Fortune Centre itself occupies a curious position in Singapore’s urban geography — an ageing mixed-use building that wears its age with a certain unpretentious dignity. The ground-floor bustle gives way, via lift or staircase, to the second floor, where Diner’s Shack occupies unit #02-31. The space is compact and unassuming; the décor, a gentle collision of East and West, features the kind of clean, functional furniture that prioritises throughput without sacrificing a certain lived-in warmth.
Midday sees the eatery at full tilt. Queues form with admirable regularity — a testament, perhaps, to the stubborn loyalty of a customer base that has learned to arrive early or accept the wait. The ambient soundscape is that of a working lunch institution: the percussive rhythm of ladles against steel pots, the hiss of gas burners, the low conversational murmur of office workers on their lunch hour. Natural light filters in from the corridor, lending the interior a softness that artificial overhead lighting rarely achieves.
There is no pretension here, and none is wanted. The ambience functions as a frame that directs the eye toward the food — and it is entirely adequate for that purpose. One does not visit Diner’s Shack for the architecture. One visits for what arrives in the bowl.
In-Depth Dish Analysis: Slice Mackerel Fish Soup ($5.50)
Presentation & First Impressions
The bowl arrives with the quiet confidence of a dish that requires no theatrical staging. At its centre, the batang (Spanish mackerel, or Scomberomorus commerson) slices command immediate attention. They are, by any reasonable standard, extraordinarily generous — thick-cut oblique slices that speak to a kitchen philosophy not yet seduced by the economics of meanness. The broth surrounds them: limpid, pale gold with a faint milky bloom at the surface, exhaling a fragrance of aged ginger and the sea.
The Soup — Colour, Clarity, and Character
Teochew fish soup is defined above all else by its broth, and here the kitchen demonstrates mastery of a deceptively demanding medium. The liquid presents as a soft ivory-gold — neither the aggressive cloudiness of a long-boiled bone broth, nor the watery transparency of a careless preparation. This is a broth that has been coaxed, not extracted: fish bones and trim simmered at a temperature below a rolling boil, yielding a stock of luminous clarity that carries genuine depth of flavour.
On the palate, the initial impression is one of clean saline sweetness — the natural inosinic acid of fresh fish meeting the gentle umami of preserved vegetables. A whisper of white pepper blooms in the mid-palate, while the finish is long and faintly mineral, the unmistakable signature of well-handled batang. Tomato and napa cabbage have been introduced to the bowl: the tomato softening and yielding its acidic brightness to the broth, the cabbage providing structural counterpoint and a mild vegetal note that grounds the dish.
The Fish — Texture, Cut, and Freshness
Batang, or Spanish mackerel, is among the most unforgiving of Singapore’s hawker fish. Its flesh, lean and firm when fresh, turns dry and fibrous with even a moment’s overcooking. The kitchen at Diner’s Shack manages this calculus with evident care. The slices — oblique cuts approximately 2cm in thickness — have been scalded in the broth to the precise moment of translucency, their interiors retaining a barely-set, almost custardy softness that yields to the slightest pressure from the tongue.
The hue of properly prepared batang tells a story: the exterior of each slice carries a faint opaqueness — a pale silver-white — while the centre, where heat has not yet fully penetrated, retains a shade of ivory-rose. This chromatic gradient is not a flaw; it is the mark of a cook who understands that carryover cooking continues in the hot broth. The flesh, once separated, exhibits that characteristic fine-grained, moist flakiness unique to the mackerel family: individual muscle bundles separating cleanly along their fascia, releasing a clean oceanic sweetness.
Supporting Ingredients — Hues and Textures
Napa cabbage contributes translucent, jade-green ribbons to the bowl. Briefly immersed, they retain a slight resistance — a whisper of crunch that persists even as they absorb the broth’s flavour. The tomatoes, cut into wedges, have softened to a state of yielding suppleness: their flesh collapsing gently, releasing a concentrated sweetness and a note of sharp acidity that cuts through the richness of the fish. Their skins, where they remain, provide the only true chromatic vibrancy in the bowl — scarlet against the ivory broth.
Ginger, julienned or sliced depending on the preparation, appears as pale amber-yellow shards. It performs a dual function: its volatile aromatics perfume the broth during cooking, while its physical presence on the palate delivers a clean, warming heat that closes each mouthful. Spring onion, finely sliced, provides the finishing note — its bright chlorophyll-green a visual counterpoint, its sharp, fresh onion flavour a final aromatic bridge between the dish’s elemental components.
“At $5.50, this bowl challenges not merely other fish soups but the very premise of what value means in contemporary Singapore dining.”
Overall Flavour Architecture
The dish succeeds because it operates within the rigorous logic of Teochew culinary philosophy: clarity over complexity, ingredient quality over artifice, restraint over showmanship. The broth is the foundation; the fish is the statement; the vegetables are the grammar that holds the sentence together. There are no jarring notes, no elements that distract or compete. Each component fulfils its assigned role with the quiet assurance of long practice.

Traditional Teochew Fish Soup — Reconstructed Recipe
The following recipe is an informed reconstruction of the dish’s likely preparation, grounded in the canonical techniques of Teochew fish soup as practised in Singapore’s hawker tradition. It is presented for educational and comparative purposes.
Ingredients (Serves 2–3)
For the Stock Base:
⦁ 500g batang (Spanish mackerel) bones and trim, rinsed
⦁ 1.5 litres cold water
⦁ 3 slices old ginger (about 5mm thickness), lightly bruised
⦁ 1 tsp white peppercorns, cracked
⦁ 1 tsp sesame oil (finishing)
For the Soup Bowl:
⦁ 300g fresh batang fillet, sliced obliquely at 2cm thickness (chilled, not frozen)
⦁ 150g napa cabbage, cut into 5cm pieces
⦁ 2 medium tomatoes, cut into 6 wedges
⦁ 2 stalks spring onion, finely sliced
⦁ Ginger, finely julienned, to garnish
⦁ White pepper, freshly ground, to finish
⦁ Salt and light soy sauce, to taste
⦁ Optional: preserved mustard greens (kiam chai), rinsed and sliced
Cooking Instructions
Step 1 — Prepare the Stock:
- Rinse the fish bones under cold water. Bring water to 80°C in a stockpot — below a full rolling boil.
- Add ginger slices and cracked white peppercorns to the cold water, then add fish bones and trim. Increase heat gently to just below boiling (80–85°C). Do not allow to boil vigorously, which emulsifies the fats and clouds the broth.
- Simmer uncovered for 20–25 minutes, skimming any foam that rises in the first 5 minutes. The resulting broth should be pale gold and translucent.
- Strain through a fine-mesh sieve, pressing gently. Reserve the clarified stock. Season with salt and a small measure of light soy sauce.
Step 2 — Prepare the Bowl: - Return the strained stock to a clean pot. Bring to a gentle simmer (approximately 90°C).
- Add napa cabbage and tomato wedges. Simmer for 3–4 minutes until the cabbage has softened but retains slight resistance and the tomatoes are just yielding.
- Add preserved mustard greens now, if using, allowing them to temper in the broth for 1–2 minutes.
- Add the sliced batang fillet. Cook for 60–90 seconds, turning once, until the exterior is opaque and the interior remains slightly translucent. Remove from heat immediately — carryover cooking will finish the fish.
- Ladle into a deep bowl. Finish with a few drops of sesame oil, a pinch of freshly ground white pepper, julienned ginger, and sliced spring onion.
Critical Notes on Technique:
⦁ Fish freshness is non-negotiable. Batang should be purchased the same morning and kept thoroughly chilled. Frozen fish yields a fundamentally different, inferior texture.
⦁ Temperature control is the defining variable. Overcooking by as little as 30 seconds transforms the flesh from yielding and moist to dry and disaggregated.
⦁ The broth must never boil. This is the fundamental rule of Teochew fish soup. A vigorous boil denatures proteins differently and introduces a cloudiness and bitterness absent from a properly controlled simmer.
Delivery Options & Accessibility
Diner’s Shack does not, to the knowledge of this publication, operate through the major third-party food delivery platforms (GrabFood, foodpanda, or Deliveroo) — a state of affairs that is, gastronomically speaking, unsurprising. Teochew fish soup is among the dishes most brutally degraded by the transit times inherent in platform delivery: the fish continues to cook in the residual heat of the broth, and what arrives at a doorstep twenty minutes after leaving the kitchen bears only a conceptual resemblance to the dish consumed on-site.
Takeaway (tapao) is available, though patrons wishing to preserve the integrity of the experience are advised to consume the soup within minutes of collection, and to request that the fish and broth be packaged separately where possible — a practice which allows for the final assembly to occur at the point of consumption.
For those unable to visit in person, the eatery may be contacted directly at 8891 2160 to enquire about collection arrangements. The official website may carry additional operational updates.
Visiting Recommendations
⦁ Arrive by 11:45am on weekdays to avoid queues. The eatery operates Monday to Friday from 11:30am, and Saturdays from 12:30pm.
⦁ No halal certification is held by Diner’s Shack — patrons with dietary requirements should note this.
⦁ Fortune Centre is accessible via Bugis MRT Station (East-West and Downtown Lines), approximately a 5-minute walk.
⦁ For seated dining during peak lunch hours, a party size of one or two is considerably more practical than larger groups.
Verdict
Diner’s Shack offers something increasingly rare in Singapore’s contemporary food landscape: a dish prepared with philosophical consistency, executed with technical confidence, and priced with a generosity that borders on the anachronistic. The Slice Mackerel Fish Soup at $5.50 is not simply good value. It is, within the parameters of its genre, a minor masterpiece of hawker cooking — a bowl that rewards attention and repays repeat visits. The broth is a lesson in what restraint can achieve; the fish, a reminder of why freshness and technique remain irreplaceable.
“In a landscape where the medium-sized, the hurried, and the merely adequate have become the norm, Diner’s Shack offers the quietly radical proposition that doing one thing very well is still enough.”
Recommended without reservation.
