Overview

Pejerrey Frito

Fried Pejerrey, Fried Silverside Fish, Pejerrey Frito de Copacabana

This pejerrey frito recipe fries lean silverside fish from Lake Titicaca in a thin, seasoned flour crust until golden and crisp, the way the lakeside restaurants of Copacabana serve it — with boiled potatoes, white rice, tomato and onion salad and lemon wedges. One serving (two fillets) is about 220 g.

Pejerrey, the silvery freshwater fish whose name means silverside, is the fish of Lake Titicaca, the high lake shared by Bolivia and Peru. In Copacabana, the Bolivian town on the lake shore, small family restaurants fry the day's catch whole or in fillets, dredged in seasoned flour, and serve it with the foods of the Altiplano: boiled potatoes, chuno, rice and a sharp tomato and onion salad. It is a lakeside lunch, eaten looking out over the water the fish came from.

Pairs well with: Boiled potatoes, white rice, tomato and onion salad, and lemon wedges

A good pejerrey frito is deep golden and crisp outside, moist and flaking inside — dry fish, a thin dredge and hot oil are what make it work.

Execution Methodology & Culinary Technique

Step-by-Step Cooking Guide

Active 40m
P

Prep Stage: Marinate and Dredge

25 Mins • Marinating, Dredging

Rinse the pejerrey fillets, pat them very dry, and drizzle with the lemon juice and a pinch of salt. Leave them to marinate for 15 minutes while you mix the flour with the salt, pepper, garlic powder and cumin in a shallow dish. Dredge each fillet in the seasoned flour, shake off the excess, and lay the coated fillets on a rack so the crust sets before frying.

Maestro Tip: Dry fish is everything: a wet fillet makes the flour slide off in the oil and leaves a patchy, soggy crust.

  1. 1

    Marinate the Fish

    15 Mins Room temperature

    Lay the pejerrey fillets in a shallow dish, drizzle with the lemon juice, and season with a pinch of salt. Turn them once so both sides are coated, then leave them to marinate for 15 minutes while you prepare the dredge.

    Do not marinate longer than 20 minutes — the lemon juice starts to firm the surface of the fish, the way it does in ceviche.

    Done when: Fillets lightly seasoned and smelling of lemon.

  2. 2

    Season and Dredge

    5 Mins Room temperature

    Mix the flour, salt, black pepper, garlic powder and cumin in a shallow dish. Lift each fillet out of the marinade, let the excess juice drip off, and press it into the flour on both sides. Shake off the excess so the coating is thin and even, then set the fillets on a wire rack.

    A thin dredge is the point of pejerrey frito: too much flour turns gummy in the oil instead of crisp.

    Done when: Each fillet evenly dusted with a thin, dry flour coat.

  3. 3

    Heat the Oil

    5 Mins Oil at 175°C (350°F)

    Pour the oil into a large, heavy pan to about 3 cm deep and heat over medium-high heat to 175°C (350°F). Test it with a pinch of flour: it should sizzle at once and turn golden in a few seconds.

    If the oil is cooler than 170°C (340°F) the fish drinks it up and turns greasy; hotter than 185°C (365°F) and the crust darkens before the fish is done.

    Done when: Oil at 175°C (350°F), flour pinch sizzling and golden.

  4. 4

    Fry the Fillets

    10 Mins Oil at 175°C (350°F)

    Slide the fillets into the hot oil away from you, two or three at a time so the oil stays hot. Fry for 3 to 4 minutes per side until deep golden and crisp, turning once with tongs. The fish is done when it flakes easily and reaches 63°C (145°F) inside. Lift out with a slotted spoon and drain on a wire rack.

    Do not crowd the pan and do not keep moving the fish — let the crust set for a full minute before you touch it, or it tears.

    Done when: Deep golden, crisp fillets; fish flakes easily and is 63°C (145°F) inside.

  5. 5

    Drain and Serve

    3 Mins Serve hot

    Season the hot fillets with a last pinch of salt, scatter over the chopped parsley, and serve at once with lemon wedges, boiled potatoes, white rice and tomato and onion salad. Fried fish waits for no one: the crust is at its best in the first few minutes.

    Serve on warm plates; a cold plate cools the crust and softens it.

    Done when: Crisp fillets on warm plates, lemon wedges ready.

Finishing Touches & Plating

Serve the pejerrey frito the moment it leaves the oil, with lemon wedges, boiled potatoes, rice and tomato and onion salad, while the flour crust is still golden and crisp.

Nutrition values are estimated — calculated from USDA FoodData Central values for the listed ingredients.

Vitamins & minerals: Vitamin B12, selenium and phosphorus from the fish, vitamin C from the lemon, and a little vitamin K from the parsley. Nutrition is estimated.

High Protein

Each serving carries about 40.5 g of protein from the pejerrey, so the plate is filling without needing a heavy second course.

B12 and Selenium

Freshwater white fish is a good source of vitamin B12 and selenium, nutrients that support normal energy levels and the immune system.

Simple Real Ingredients

The plate is built from fish, flour, lemon and oil — a short list of real ingredients with no ready-made coating or sauce.

Food Pairings

What to Eat With

To optimize nutrient absorption and elevate the sensory depth, pair with these authentic accompaniments:

Sides

Boiled Potatoes and Chuno

Plain boiled potatoes — and chuno, the freeze-dried potato of the high Andes, where you can find it — are the traditional partners: mild, starchy and perfect for soaking up lemon juice.

White Rice

Steamed white rice gives the plate a soft, neutral base that lets the crisp fish and sharp lemon stand out.

Vegetables

Tomato and Onion Salad

Sliced tomato and onion with oil and salt cuts the richness of the fried crust and refreshes the palate, the way the lakeside restaurants serve it.

Drinks

Cold Lager

A cold, light lager matches fried fish the way it does everywhere on the coast and the lake: cold, crisp and cleansing between bites.

Complete menu

Serve two pejerrey frito fillets per person with boiled potatoes, white rice, tomato and onion salad and lemon wedges, and finish with a cold lager.

Digestive Guardrails

What NOT to Combine

To prevent digestive distress, sluggishness, or palate clash, avoid pairing the dish with these elements:

Do Not Fry in Cool Oil

Oil below about 170°C (340°F) soaks into the flour instead of crisping it, leaving greasy fish and a soft crust. Keep the oil at 175°C (350°F) and let it come back to temperature between batches. This is general food information, not medical advice.

Do Not Serve Undercooked Fish

The fillets must reach 63°C (145°F) inside and flake easily; pale, soggy crust means the oil was too cool, and fish that smells off should be discarded, not tasted. This is general food-safety guidance, not medical advice.

General information only, not medical advice — consult a doctor for personal dietary decisions.

Who Should Eat It

Who Should Eat

  • General adultsA satisfying high-protein lunch — two fillets with potatoes, rice and salad is a full plate.
  • ChildrenFine for older children in small pieces, but pick out any fine bones carefully and let the fish cool for a minute.
  • ElderlyRich in B12 and selenium and easy to chew once the bones are out; serve a smaller fillet with extra salad.
  • Pregnant womenEat only fully cooked fish at 63°C (145°F) inside, from a fresh source; skip raw or undercooked fish. Ask your clinician about fish during pregnancy.
  • Breastfeeding womenA good source of protein and B12; keep portions moderate and favour the salad over extra fried pieces.
  • AthletesA solid post-training meal with about 40.5 g of protein; the potatoes or rice add recovery carbs.
  • Weight gainA calorie-dense plate at 333 kcal that builds up easily — add an extra fillet and more potatoes and rice.
  • Weight lossThe fish is filling at 333 kcal — keep to one fillet with a large salad and skip the rice.

Health Conditions — Adjust or Avoid

Conditions

  • DiabetesThe dredge adds about 13.2 g of carbs per serving — keep the potatoes or rice small and load up on the tomato salad. Ask your clinician about portion size.
  • High blood pressureThe plate carries about 624 mg of sodium, mostly from the seasoning salt — use less salt and skip extra salty sauces. Ask your clinician about sodium limits.
  • Kidney diseaseHigh in protein (about 40.5 g), so it may not suit a restricted-protein diet. Ask your clinician before eating it.
  • GoutWhite fish is low in purines compared with red meat and shellfish, but the plate is rich — keep portions moderate if you have gout. Ask your clinician for personal advice.
  • Stomach issuesFried food and raw onion can irritate a sensitive stomach — try a small portion first and eat it freshly fried, not reheated. Ask your clinician if symptoms persist.
  • Cardiovascular diseaseThe fish itself is lean, but frying adds fat and salt — keep portions moderate, drain well and favour the salad. Ask your clinician about fried foods in your diet.
  • Fatty liverFried food is calorie-dense at 333 kcal per serving — watch the total portion and skip a second fillet. Ask your clinician about suitable portion sizes.
  • Food allergiesContains fish and gluten (wheat flour). Ask your clinician if you have a fish or gluten allergy.
  • Special therapeutic dietsNot suitable for a gluten-free or low-fat therapeutic diet as written; a rice-flour dredge and baking instead of frying would be needed. Ask your clinician or dietitian before eating it.

If you have a medical condition, consult your doctor before changing your diet.

Storage & Use

Storage & Use

How to store
Cool the fillets on a wire rack, then store in a covered container lined with paper towel; store the salad separately.
In the fridge
2 days for the cooked fish; eat the salad the same day.
In the freezer
Not recommended — the crust goes soggy and the fish dries out on thawing.
How to reheat
Reheat in a 200°C (400°F) oven on a wire rack for 6 to 8 minutes until crisp and steaming hot all the way through, to 74°C (165°F). Never reheat fried fish in the microwave.
Freezing recommended
No — best eaten fresh; freeze the raw fillets instead, before dredging.
Signs it has spoiled
Sour or fishy smell stronger than fresh fish, slimy coating, or a crust that smells stale — discard, do not taste to check.

Bolivian Salteñas

A Bolivian salteña is a baked hand pie with a slightly sweet, golden dough — coloured with paprika or annatto — sealed with a braided seam across the top and baked standing upright. Inside is the jigote, a juicy beef stew of diced beef, potato, onion, peas and ají chilli, sweetened with a few raisins and set with gelatin so it turns to rich broth in the oven, with a slice of hard-boiled egg and a black olive tucked in. This is not a dry mince empanada: you bite a small corner, then spoon and sip the hot juices out. One serving (two salteñas) is about 462 g.
