Ceviche con Palta

Peruvian white fish ceviche with avocado, ají amarillo tiger's milk and choclo corn on a bed of sweet potato

Origin: Lima, Peru

From the journey of Avocado.

Ceviche is Peru's national dish, its cultural identity, and one of the greatest expressions of any cuisine on earth. The word itself is ancient, almost certainly derived from a Quechua term for marinated or fermented food, but the modern form as practised in Lima's cevicherías is a product of centuries of layered cultural exchange: the pre-Incan coastal tradition of curing fish in the juice of the tumbo fruit (a wild passion fruit native to the Andes), the arrival of Spanish citrus in the sixteenth century, and the wave of Japanese immigration in the late nineteenth and early twentieth centuries that brought the precision and aesthetic sensibility of Japanese raw fish preparation to the Peruvian kitchen, producing the Nikkei cuisine of which modern ceviche is the supreme example. The leche de tigre (tiger's milk, the citrus-and-chilli curing liquid in which the fish is briefly macerated) is the soul of the dish: a marriage of fresh lime juice, ají amarillo (Peru's definitive orange-yellow chilli, hot and fruity), garlic, ginger, and fish stock, balanced to a precise knife-edge between acid, heat, and sweetness. The fish is not cooked in the conventional sense: the citric acid denatures the proteins on the surface of each cube, producing a firm, white exterior that looks cooked while the interior retains a silky, almost raw texture that a poached fish can never have. The palta (the Peruvian avocado) is served alongside as the essential counterweight: its cool, dense fat absorbing and amplifying the bright acid of the leche de tigre, its creaminess cutting the heat of the chilli, its green a visual counterpoint to the white of the fish and the orange of the sweet potato. This is not garnish. This is architecture.

Ingredients

Ceviche

500 g very fresh firm white fish (sea bass, sole, or corvina), cut into 2 cm cubes
1 tsp fine sea salt
1 small red onion, very finely sliced into half-moons
3 tbsp fresh coriander leaves, roughly torn

Tiger's Milk

150 ml fresh lime juice (about 6–8 limes), freshly squeezed
50 ml light fish stock or water
1–2 ají amarillo chillies, seeds and veins removed, roughly chopped (or 2 tbsp ají amarillo paste)
1 small clove of garlic, roughly chopped
2 cm piece of fresh ginger, peeled and roughly chopped

To Serve

2 large ripe Hass avocados (palta), halved, stoned and sliced
1 large orange sweet potato (camote), peeled, boiled until just tender and sliced into rounds
100 g choclo (Peruvian giant corn), cooked, or substitute with tender sweetcorn kernels
extra fresh coriander and thinly sliced red chilli, to finish

Method

Make the tiger's milk: blend the lime juice, fish stock, ají amarillo (or paste), garlic, and ginger until completely smooth. Pass through a fine sieve. Taste: it should be sour, hot, and very aromatic. Add salt as needed. Keep cold.
Season the fish cubes lightly with the sea salt. Place in a cold bowl (chilled in the freezer for 5 minutes if your kitchen is warm). Add the sliced red onion and pour the tiger's milk over the fish. Toss gently and leave to marinate for exactly 3–4 minutes: no more.
Add the torn coriander leaves and toss once more. Taste and adjust salt or a drop more lime if needed.
To plate: arrange sweet potato slices on one side of each cold plate. Fan several slices of avocado alongside. Spoon the ceviche over the centre. Scatter with choclo corn, extra coriander, and sliced chilli. Drizzle a little of the remaining tiger's milk over everything. Serve immediately.

Notes

Freshness of the fish is non-negotiable. Buy sushi-grade or sashimi-grade fish and use it the same day. Corvina (white sea bass) is the traditional Peruvian choice; good British sea bass, halibut, or sole are excellent alternatives. Ají amarillo paste is available in Latin American grocery stores and online: it is difficult to substitute without changing the character of the dish. If unavailable, a combination of a mild orange chilli and a small amount of turmeric (for colour) approximates the flavour imperfectly.
