Overview

Barranco celebration ceviche with fish and prawns — measured ingredients, clear preparation and safe seafood handling

Ceviche is documented as food for ordinary meals and shared celebrations, while its ingredients vary across Peru. This Barranco celebration-table arrangement applies that flexibility to fish and precooked prawns, with camote, choclo and cancha portioned on individual plates. It is not described as a ritual dish specific to Barranco.

The combination of the two seafood textures makes the platter feel different from a fish-only lunch portion. Corvina-type fish remains firm and evenly diced; the cooked prawns should be thoroughly chilled before use. Serving the soft sweet potato, chewy maize and crisp cancha separately protects their individual textures.

The preparation may be for a gathering, but it must not spend the gathering at room temperature. Chop and plate the accompaniments first, hold the fish and prawns in the refrigerator at no more than 4 °C, and toss them with lime only at service. This retains the character of ceviche without suggesting that citrus disinfects raw fish.

Ingredients

Main

480 g corvina or another firm white marine fish fillet — skinless, boneless, previously frozen under supplier-controlled raw-fish parasite procedures; fully thawed and kept at 4 °C or below
180 g red onion — peeled, sliced paper-thin
180 ml fresh lime juice — just squeezed, strained; measured juice, not whole fruit
20 g ají limo — deseeded and finely chopped; handle with clean utensils
16 g fresh coriander leaves (culantro) — washed, dried and finely chopped
3 g fine salt — measured

Seafood

240 g cooked peeled prawns — fully cooked, promptly chilled and kept at 4 °C or below

To serve

320 g cooked camote (sweet potato) — peeled, sliced, chilled ready to eat
180 g cooked choclo kernels (large-kernel Peruvian maize) — drained and chilled ready to eat
80 g cancha (toasted maize kernels) — ready to eat, unsalted

Method

Check the cooked accompaniments.Arrange cooked camote (sweet potato), cooked choclo kernels (large-kernel Peruvian maize), cancha (toasted maize kernels) in separate piles on four clean cold plates. All cooked components must already be thoroughly prepared and cold. Leave crisp garnishes dry, off the lime-dressed fish. Allow 4 minutes for this step. The cooked accompaniments are cold and separate, and any crisp garnish remains dry. Safety: Use ready-to-eat cooked starches and legumes from refrigeration, not raw beans or cassava.
Prepare the vegetables.Use a clean vegetable board to slice the red onion into thin feathers and finely chop the ají limo and washed coriander. Measure the fresh lime juice in a separate cold bowl; avoid bitter pith and pips. Allow 5 minutes for this step. The onion strips are thin enough to bend and the chopped pepper and coriander are evenly fine. Safety: Wash hands and tools before moving to the raw fish.
Dice the refrigerated fish.On a separate, freshly cleaned board cut 480 g of chilled boneless white fish into even 1.5–2 cm cubes; transfer to a cold non-reactive bowl. Keep it at 4 °C or below until all plates and seasonings are ready. Allow 4 minutes for this step. The cubes have even edges, no visible bones and a firm texture. Safety: Use only professionally sourced raw-use fish; previously frozen fish still carries microbial risk and must stay at 4 °C or below.
Bring in the cooked prawns.Open the ready-cooked chilled prawns, weighing 240 g. Move them directly into a separate cold serving bowl with a clean spoon; never place them on the raw-fish board. Allow 3 minutes for this step. Each prawn is fully cooked and cold, with no off odour or slippery film. Safety: Keep fully cooked prawns at 4 °C or below; if they were sold raw, cook separately to 63 °C before chilling them completely, outside the stated quick-assembly schedule.
Season and toss.Sprinkle the fish with 3 g fine salt, fold through the ají limo and coriander, then add 180 ml measured lime juice and the sliced red onion. Turn gently so all the cubes are wetted. Allow 3 minutes for this step. The fish cubes are evenly coated with juice without crumbling, and the onion is dispersed throughout. Safety: Citrus is seasoning, not a validated control of fish parasites or harmful bacteria.
Finish with prawns and plate.Fold the cold, fully cooked prawns through the fish mixture once, then distribute all the seafood and its juice over four plates, keeping the prepared side dishes separate. Allow 3 minutes for this step. Each plate has both fish cubes and intact prawns; cold sides have kept their shape. Safety: Serve immediately; do not let the finished raw-fish dish sit unchilled.

Practical

Keys to success

Prepare everything except the acid toss ahead; do not leave the seafood buffet-style without active chilling. Use a retailer who understands and can document seafood intended for raw consumption.

Serving and practical guidance

This is a practical celebration-table variation. Its distinguishing service detail is two seafood textures and three portioned garnishes. The accompaniments are ready-cooked, chilled or packaged as described in the ingredient list; starting from dry beans or raw cassava would require a separate, additional cooking session, not included in the 27-minute assembly schedule. For advance preparation, refrigerate measured lime juice and separately packed washed vegetables, cooked sides and raw fish at or below 4 °C. Keep crisp chips or toasted maize sealed and dry. Once the lime reaches the fish, plate straightaway; a longer marinade is not required for flavour and cannot guarantee microbial or parasite safety. Discard any raw fish that arrives warm, smells sour or ammonia-like, or shows signs of poor handling. Never use a cooked-side preparation board for raw fish without washing and sanitising it. Do not store dressed raw-fish leftovers for a later meal. For diners at higher risk of foodborne disease, prepare a fully cooked fish option instead of this raw recipe. The prawns are explicitly precooked and refrigerated: raw prawns cannot simply be folded into the mixture on the assumption that lime will cook them. Keep them cold in their own clean dish until the final toss. This extra seafood ingredient means the finished plate contains both fish and crustacean shellfish allergens.

Control points

Texture issueFish becomes chalky or ragged if left too long in the acidic dressing; mix just before serving.
Serving issueA damp garnish loses snap; keep fried or toasted garnishes separate from liquid.

Allergens and food safety

Allergens: Fish and crustacean shellfish. Check packaged accompaniments, cheese and supplier practices for additional cross-contact where applicable. The nutrition figures are estimates for the quantities listed; the stated sodium total includes the measured salt and inherent sodium in the foods. Use fish supplied specifically for raw preparations, with documented suitable parasite-control freezing or equivalent supplier controls. Previously frozen fish is not free of all microbial risks. Cooked prawns are a crustacean allergen; hold them separately from raw fish until assembly and keep chilled. Keep all seafood and cooked accompaniments refrigerated at 4 °C or below, and clean hands, tools and worktops after handling raw fish. Fresh lime acid changes fish texture; it does not reliably kill parasites or bacteria. Serve immediately, do not hold at room temperature, and do not save leftover dressed raw seafood for later service. Pregnant people, children, older adults and those with weakened immunity should avoid raw or undercooked seafood; a fully cooked fish meal is a safer alternative.

Closing

Result: Two seafood textures and three portioned garnishes, served cold with clearly differentiated seafood and accompaniments.
Critical control: Prepare everything except the acid toss ahead; do not leave the seafood buffet-style without active chilling.
