Tiritas are Zihuatanejo's signature ceviche: thin strips of very fresh raw fish cured briefly in lime juice with slivered onion, sliced serrano or habanero chile and salt — and almost nothing else. Cut into strips rather than the usual cubes, the fish is dressed and eaten within minutes, while it is barely turned at the edges and still nearly raw. Spare and bright, it is the coastal antithesis of a heavy, tomato-laden cocktail, usually served with tostadas, lime and a cold beer.
Tiritas are the signature dish of Zihuatanejo, the fishing town on Guerrero's Costa Grande, and a relatively young one — local accounts place their birth around the mid-twentieth century. The origin stories agree on the shape of the thing: local boat captains and fishermen, out at sea with only the day's catch, limes, onion and salt, sliced the fish into thin strips and dressed it on the spot. Several Zihuatanejo fishing families — the name of Alfonso Lara recurs, along with other captains — are remembered for popularizing it, and one telling has the strips served to early Japanese visitors. From those pangas it became the town's emblem.
Translucent ribbons of white fish, glossy and just firmed at the edges by the lime, piled with crisp slivers of raw onion and thin rings of green chile. The first hit is bracing lime acidity, then clean sweet fish, then a building heat from serrano or the fruity burn of habanero, all kept sharp by salt — no tomato, no ketchup, no clutter. The fish stays silky and yielding, not cooked-firm. Scooped onto a snapping tostada, it is cold, sour, fiery and fresh all at once.
The cure is a controlled denaturation: citric acid in lime juice unwinds the proteins on the fish's surface, firming and whitening them much as heat would, but only as deep as the acid penetrates in the brief time given. Cutting the fish into thin strips is the whole technique — more surface, less thickness, so the lime grips the outside fast while the interior stays raw, silky and sweet. That is why tiritas are dressed and eaten almost immediately; left to sit, the acid drives all the way through, the flesh turns opaque, firm and chalky, and the prized just-raw center is lost. Very fresh, firm white fish and barely-there marinating time are non-negotiable.
Variations
The fish is whatever came in fresh — sierra (Pacific mackerel), snapper, or other firm white fish; heat ranges from sliced serrano to the fiercer, fruitier habanero favored along this coast. Some cooks add cucumber for crunch, a little cilantro, or a few drops of a clear hot sauce, though purists keep it to fish, lime, onion, chile and salt. It sits within the wider family of Mexican ceviches and the raw aguachile of the northern Pacific, but stays defined by its strips and its near-raw bite.
On the Palate
Where Tiritas de Pescado sits in the Mexican flavor cloud
Slice the fish into thin finger-width strips and dress with lime only a few minutes before eating — the acid firms just the surface while the center stays raw and silky, and left too long it drives all the way through to chalky.

How it's made
7 steps · 20 min active + 5 min waiting
- 15 min
Choose very fresh, firm white fish and chill it well before cutting.
- 26 min
Slice the fish across the grain into thin strips about the width of a finger.
Watch outCut across the grain into even finger-width strips so they cure at the same rate and stay tender.
- 34 min
Sliver the white onion thinly and cut the serrano or habanero into fine rings or slices.
- 44 min
Toss the fish with plenty of fresh lime juice and salt until the strips just begin to firm and turn at the edges.
Watch outToss just until the strip edges turn white and firm slightly; the moment they whiten at the rim, stop.
- 53 min
Fold in the onion and chile and let it sit only a few minutes.
Watch outRest only a few minutes after the onion and chile go in — long enough to mingle, not to cook through.
- 62 min
Taste and adjust lime and salt, keeping the center of the fish still raw and silky.
- 71 min
Serve at once, cold, with tostadas and lime wedges.
