Chupe de Camarones (Arequipa River Prawn and Milk Chowder)

// SUPPLY LIST

// OPERATIONS

1. 1 Twist the heads off the prawns and reserve every single one, along with any soft orange coral clinging inside them; peel the bodies, leaving the tail fan attached, pull out the dark vein with a knife tip, and keep the peeled bodies covered in the fridge until the very last step. Reserve the shells with the heads. The heads and their coral are the entire flavour engine here — a chupe built from pre-peeled prawns is milk soup with potatoes in it, and nothing you add later will disguise that.
2. 2 Set a 28 cm (6-7 litre) heavy-bottomed pot over medium-high heat with 45 ml of the oil. When it shimmers (roughly 180 C / 356 F), add the heads and shells in one layer and fry for 6-8 minutes, crushing them hard against the base with a potato masher every 30 seconds, until the shells are deep brick-red, the coral has melted out and stained the oil bright orange, and the pot smells sweet and toasted. Drop the heat to medium the moment any shell starts to blacken — scorched heads turn the whole pot acrid and there is no recovery from it.
3. 3 Pour in the 2.5 litres of cold water, bring to a bare simmer (90-95 C / 194-203 F, surface trembling with only the odd bubble breaking) and hold it there uncovered for 25 minutes; do not let it roll, which emulsifies the shell proteins and gives you a cloudy, chalky-tasting stock. Strain through a fine sieve into a bowl, pressing the solids firmly with a ladle to drive out the last of the coral, then discard the shells — you should have about 2 litres of coral-orange stock.
4. 4 Rinse the pot, wipe it dry and return it to medium heat with the remaining 45 ml oil, bringing the oil to a gentle ripple with no smoke (about 140-150 C / 285-300 F); cook the diced onion for 8-10 minutes, stirring often, until it is fully translucent and just beginning to gold at the edges, then add the garlic and cook 1 minute more, until it smells sweet but has taken no colour — garlic browned at this point turns bitter and you will taste it straight through the milk.
5. 5 Stir in the ají panca and ají amarillo pastes and fry over medium-low (the mass should sizzle quietly, not spit) for 4-5 minutes, stirring constantly, until the paste darkens by a shade and a clear rim of red oil separates around the edge. This is the step home cooks skip, and underfried ají tastes raw, dusty and faintly metallic all the way through the finished soup. Add the grated tomato, oregano and cumin and cook a further 5-6 minutes, until the mixture is jammy and the spoon leaves a clean track across the base of the pot.
6. 6 Pour in the strained prawn stock, bring back to a gentle simmer (about 95 C / 203 F), season with 2 tsp fine salt as a base — not the final seasoning — then add the choclo rounds and simmer uncovered for 10 minutes, until a kernel prised off with a knife tip is tender and milky rather than squeaky.
7. 7 Add the potatoes, the squash and the rinsed rice together and hold at a lazy simmer — small bubbles at the edge only, around 92-95 C / 198-203 F, never a rolling boil — for 15-18 minutes, stirring up from the base every few minutes so the rice cannot settle and catch, until a skewer slides into a potato chunk with only the faintest resistance and the squash has collapsed completely into the broth, thickening it to the consistency of single (pouring) cream. That dissolved squash, not flour or cornflour, is what gives a real chupe its body; if you thicken this soup with starch you have made something else, and if you put the rice in any earlier it will be paste by the time the eggs go on.
8. 8 Add the habas and simmer for 5-6 minutes more, until tender but still bright green, then taste the broth and correct the salt and pepper — expect to need another 1-2 tsp of salt at this point. It should read a shade too savoury now, because the 400 ml of evaporated milk and the cheese still to come will round it off and mute it.
9. 9 Turn the heat to its lowest setting, stir in the evaporated milk and all but six small leaves of the huacatay (keep those back for the bowls), and bring the pot only to 82-85 C / 180-185 F, where the surface shivers but never bubbles. From here the soup must not boil: it will break into grainy curds under a slick of orange fat and cannot be stirred back together. Jarred huacatay paste is what most Arequipeña kitchens use midweek and is entirely legitimate — 1 tbsp, stirred in here — but ordinary mint is not a substitute for it and drags the milk somewhere medicinal.
10. 10 Crack the 6 eggs straight onto the surface, spaced well apart so they do not touch, cover the pot and hold at that same 82-85 C / 180-185 F for 3 minutes; then slide the peeled prawn bodies gently in around them, re-cover, and give it a further 3-4 minutes, until the whites are completely opaque, the yolks still soft beneath a thin veil, and the prawns have curled into a loose C and turned coral-pink and opaque right through. The prawns go in second because they need half the time the eggs do, and nothing must be stirred at this stage or the whites shred into rags through the broth; a prawn coiled into a tight O has gone too far and will eat like cotton wool.
11. 11 Scatter the queso fresco cubes over the surface, put the lid back on, take the pot off the heat altogether and let it rest for 2-3 minutes; the cheese should soften and go creamy at the edges while still holding its shape. Stirred in any earlier it strings out and vanishes into the broth.
12. 12 Serve straight away, ladling from the bottom so every deep bowl gets potato, choclo, habas, prawns and cubes of cheese, and lifting one whole egg into each bowl with a slotted spoon; finish with a reserved huacatay leaf and a grind of black pepper. Chupe does not survive reheating — the yolk hardens and the milk splits — so cook it to the table, and pass rocoto salsa, lime wedges and crusty bread alongside.
