Milkfish is butterflied open down the back, then steeped in vinegar, a heavy hand of crushed garlic, salt, and black pepper for several hours or overnight. The acid-and-garlic bath lightly cures and seasons the flesh before it is pan-fried or fried crisp, skin-side blistered and golden. It is one of the cornerstones of the Filipino silog breakfast — paired with garlic rice and a fried egg it becomes bangsilog — and arrives with a saucer of spiced vinegar for dipping. The marinade is a kitchen descendant of daing, the old island practice of splitting and curing fish to keep it.
Daing is a pre-colonial island technique in which fish is split open from the back, gutted, salted, and dried to keep it through lean stretches — a food-security staple long before refrigeration, documented in early accounts of indigenous practice. Daing na bangus is the marinated, fresh-cooked cousin of that tradition: rather than salting and sun-drying for days, the butterflied milkfish is steeped briefly in vinegar and garlic and then fried, so the flesh stays moist instead of toughening. Bangus, the milkfish raised in coastal fishponds across the archipelago, is popularly spoken of as the national fish, though the National Commission for Culture and the Arts notes the title has no legal basis. The vinegar-garlic version anchors the modern silog breakfast.
Crisp, blistered skin shatters over moist white flesh that carries a clean sour tang from the vinegar and a deep roasted-garlic warmth, the spiced dipping vinegar sharpening each forkful with a fresh hit of acid and chili.
Vinegar's acetic acid lowers the surface pH of the fish, unfolding (denaturing) the outer proteins much as gentle heat would — the same principle as ceviche — so the exposed flesh firms, takes on tang, and gains a measure of keeping quality as the acid suppresses spoilage microbes. The effect is deliberately shallow, reaching only the outer few millimeters; an overnight steep is safe for milkfish, but a far longer one would over-break the delicate protein and turn it mushy. Salt draws out surface moisture and seasons throughout by diffusion, while the acid leaves the skin slightly dried and tacky. In the hot pan that dried surface crisps fast and browns through the Maillard reaction between its amino acids and sugars, giving the golden, blistered crust against the still-moist interior.
Variations
Cane vinegar is the common base, but coconut or palm vinegar gives a rounder, fruitier sour. Many cooks add bruised whole peppercorns, bay leaf, or a little chili to the marinade, and some splash in soy sauce. The fish may be shallow pan-fried for tender flesh or deep-fried hard for a shatter-crisp shell, then drained. Boneless bangus fillets are now sold pre-marinated for convenience, and the same daing cure is applied to other fish such as tilapia or galunggong.

8 steps · 20 min

Butterfly the bangus down the back, open it flat, gut and rinse it, then pat dry.
- 23 min
Crush the garlic and combine with vinegar, salt, and ground pepper to make the marinade.
- 3240 min
Lay the fish flesh-side down in the marinade, cover, and refrigerate 4 hours to overnight.
Watch outSteep in the vinegar marinade only to overnight, no longer — the acid firms the outer flesh, but too long and it over-breaks to mush.
- 43 min
Lift the fish out and let excess marinade drip off; pat the surface dry so it will crisp.
- 53 min
Heat oil in a wide pan until shimmering.
- 68 min
Fry skin-side first over medium-high heat until blistered and golden, then turn and fry the flesh side through, about 6 to 8 minutes total.
Watch outFry skin-side first until blistered and golden before turning — a well-dried, well-crisped skin is the payoff of the cure.
- 72 min
Drain on a rack or paper.
- 83 min
Serve hot with garlic rice, a fried egg, and a saucer of spiced vinegar for dipping.
