Rocoto relleno is the flagship dish of Arequipa's picanterías: a fat red rocoto, seeded, deveined and blanched three times in sweetened vinegar water, then stuffed with a beef picadillo of raisins, peanuts, olives and hard-boiled egg, capped with queso paria and baked in a shallow bath of evaporated milk and egg that sets to a custard around it. Unlike almost every other Peruvian main, the chilli here is the dish rather than the seasoning, and the blanching exists to bring the rocoto down to a heat you can eat a whole one of, not to erase it. A good one still burns pleasantly, the walls hold their shape under a fork, and the filling is dry and savoury enough to stand up to the pepper's sweet-sour edge. It is served with pastel de papa, the Arequipeño potato-and-milk gratin.

| 6 | Large red rocoto peppers (about 180 g each), lids cut off with the stems attached, seeds and pale inner ribs completely removed | |

| 250 | g | Red onion, cut into 3 mm dice |

// OPERATIONS
- 1 Put on disposable gloves before you touch the rocotos and keep them on until the peppers are blanched: rocoto capsaicin transfers to skin and stays there for hours, and it will find your eyes later. Cut a lid off the top of each pepper about 1 cm down from the shoulder, keeping the stem attached to the lid as a handle, and set the lids aside. With a teaspoon, scrape out every seed, then shave away the pale waxy ribs standing proud of the inner wall until it is smooth. Those ribs, not the seeds, carry most of the heat, and leaving them is the single most common reason a home rocoto relleno comes out inedible. Rinse shells and lids under cold running water.
- 2 Bring 2 litres of water to a rolling boil in a 5 litre stainless or enamelled pan (not bare aluminium, which reacts with the vinegar and tastes metallic). Add 40 g of the sugar, 60 ml of the vinegar and 1 tbsp of the salt, slide in the shells and lids, and hold them under the surface with a heatproof plate. Boil hard for 3 minutes from the moment the water returns to the boil, drain into a colander, discard the water, and repeat twice more with completely fresh water, sugar, vinegar and salt: three separate baths, about 30 minutes all in counting the reboils. Do not compress this into one long boil. Capsaicin leaches into hot water only slowly, and a bath already carrying it stops drawing out more, so nine minutes in one saturated pan pulls far less heat while cooking the walls to mush.
- 3 After the third bath, test before you go further: tear a 5 mm fragment from the cut rim of one pepper and chew it. It should read hot and fruity, a burn that builds and then recedes, assertive but survivable. If it still stabs at your lips after 30 seconds, run a fourth bath. Stand the shells and lids upside down on a rack for 15 minutes to drain; the walls should be pliable and slightly translucent but firm enough to spring back when pressed.
- 4 Heat the oil or lard in a 28 cm heavy-based sauté pan over medium heat until it shimmers, add the diced red onion with 1 tsp of the fine sea salt, and cook 8-10 minutes, stirring often, until it is completely translucent and only just gilding at the edges. It must not brown properly or the filling turns sweet and faintly bitter. Stir in the garlic and cook 1 minute more, until fragrant but uncoloured.
- 5 Add the ají panca paste and fry it, stirring constantly, for 3-4 minutes over medium heat until it darkens from bright red to brick and a rim of red oil separates out around the edge of the pan. Adding the meat before the paste has fried out leaves a raw, dusty chilli flavour through the whole dish that no amount of later simmering will cook away.
- 6 Raise the heat to medium-high, add the beef, and cook 6-8 minutes, breaking it up with a wooden spoon, until no pink remains and, more importantly, the juices it throws off have boiled away and the meat starts to sizzle and fry rather than steam. Stir in the cumin, crumbled oregano and black pepper and cook 1 minute to bloom them.
- 7 Pour in the stock, add the raisins, and simmer 5 minutes over medium heat until the raisins are plump and the pan floor stays dry for a full second behind a dragged spoon. A wet picadillo bleeds into the milk during baking and splits it. Off the heat, fold in the peanuts, olives and the 3 chopped eggs, then season with the remaining 1 tsp fine sea salt: it needs to taste noticeably saltier than seems right on its own, because the blanched rocoto is sweet and sour and will mute it. Spread the filling on a tray and cool to room temperature, about 25 minutes, so it does not slacken the pepper walls. You should have around 850 g.
- 8 Heat the oven to 180°C/350°F (fan 160°C/325°F) and butter a 26 x 20 cm ceramic or glass baking dish, snug enough that the six shells stand touching and hold one another upright. In an oversized dish they topple and the milk spreads too thin to set. If one still leans, wedge a small ball of crumpled foil between it and the dish wall rather than trimming its base, which would let the filling drain straight out.
- 9 Blot the inside of each shell dry with kitchen paper, then pack in about 140 g of the cooled picadillo, roughly three heaped tablespoons, pressing lightly with the back of a teaspoon and stopping 5 mm below the rim. A little filling left over is normal and better than the alternative: overfilled peppers push their lids off and spill as the filling swells in the heat.
- 10 Lay a round of hard-boiled egg on each, then a 1 cm slab of queso paria across the opening so it overhangs the rim slightly, and rest the stemmed lid on top at a slight angle so a crescent of cheese stays exposed and can brown. A lid pressed down flat seals the cheese in and it steams to a pale rubbery disc instead of blistering.
- 11 Whisk the evaporated milk with the 2 beaten eggs and 1/2 tsp fine sea salt and pour it around the base of the peppers to a depth of about 1.5 cm, roughly a third of the way up their sides: around them, never over them, because milk poured on top washes the cheese off and steams it pale instead of browning it. Bake 35-40 minutes, until the milk has set to a custard that wobbles as one piece when you nudge the dish, the exposed cheese is bubbling and freckled brown, and the shoulders of the rocotos have darkened and gone glossy and slightly blistered. If the cheese is still white at 40 minutes, give it 2-3 minutes under a hot grill and do not walk away.
- 12 Rest the dish 10 minutes out of the oven before serving; straight from the heat the filling is molten and the custard too loose to lift cleanly. Serve one rocoto per person on a warm plate with a spoonful of the set milk from the dish and a wedge of pastel de papa, the Arequipeño potato-and-milk gratin that is its inseparable partner. The pepper is eaten whole, walls and all. Pour cold beer or chicha de jora, and keep a glass of plain milk on the table for whoever the heat gets ahead of.
