Squid Ink Spaghetti with Seared Calamari, Red Prawns and Colatura di Alici | Spaghetti al Nero di Seppia con Calamari Scottati, Gamberi Rossi e Colatura di Alici
Updated: 2 days ago
This is a Tyrrhenian plate built on three ingredients that never meet in a traditional kitchen. Black spaghetti carries the mineral bitterness of cuttlefish ink. Calamari goes into a very hot pan for less than a minute and comes out sweet and lightly caramelized. Raw red prawns are laid on at the last second and warmed only by the pasta. Binding all of it is colatura di alici, the amber anchovy liquid of Cetara, used cold and never cooked.
The discipline of the dish is salt. Colatura is one of the saltiest condiments in Italian cooking, and everything upstream of it has to be adjusted downward: the pasta water is salted at roughly half strength, no salt goes near the seafood, and the emulsion is tasted before a single grain is added. Cooks who treat colatura as an ordinary seasoning produce a plate nobody can finish.
What makes it worth the precision is contrast. The ink is savoury and faintly bitter, the prawns are sweet, and the anchovy runs underneath as depth rather than as a flavour you can name. Nothing here is complicated. Everything here is a matter of timing measured in seconds.
Yield: 4 servings. Prep: 30 minutes. Cook: 15 minutes. Total: about 45 minutes. Difficulty: intermediate. Course: primo piatto. Region: Campania and the Tyrrhenian coast.
The Story
Colatura di alici comes from Cetara, a fishing village wedged into a ravine on the Amalfi Coast. Anchovies caught between spring and early summer are beheaded, gutted, layered with sea salt in a chestnut barrel called a terzigno, weighted with a wooden disc and stones, and left until autumn. The liquid that works its way out is drawn off, filtered through linen, and returned to the barrel to pass back through the fish. What emerges in December is clear, amber and extraordinarily concentrated. Most of Italy discovered it only in the last thirty years.
Its ancestry is Roman. Garum, the fermented fish sauce that seasoned almost everything on a Roman table, was produced industrially along this coast, and the vats at Pompeii are a short drive from Cetara. When the empire fell the trade collapsed everywhere except in a handful of monastic and village kitchens, and colatura is the surviving thread. The classic Cetara dish, spaghetti alla colatura, is eaten on Christmas Eve with nothing but the sauce, garlic, parsley, oil and chilli.
The other two elements arrive from elsewhere on the same sea. Cuttlefish ink pasta belongs to Venice and to Sicily rather than to Campania, and gamberi rossi, the deep water red prawns, come up mainly from Mazara del Vallo. Putting them together is a modern move, and an honest one: this is not a village recipe with a grandmother behind it. It is a composition that works because all three ingredients grew up in the same water.
Ingredients
For the pasta
Squid ink spaghetti, dried, 12 oz (340 g)
Water for boiling, 5 quarts (4.7 liters)
Coarse sea salt for the water, 1 1/2 tbsp (25 g), half the usual amount
For the seafood
Fresh calamari, cleaned, bodies and tentacles, 10 oz (285 g)
Red prawns, gamberi rossi, shell on, 8 large
Extra virgin olive oil for searing, 1 tbsp (15 ml)
For the sauce
Colatura di alici di Cetara, 2 1/2 tbsp (37 ml)
Extra virgin olive oil, 5 tbsp (75 ml)
Garlic cloves, lightly crushed, 2
Fresh red chilli, seeded and minced, 1 small, or dried flakes, 1/2 tsp (1 g)
Cuttlefish ink, 1 tsp (5 g)
Flat leaf parsley, finely chopped, 2 tbsp (6 g)
Reserved pasta cooking water, about 3/4 cup (180 ml)
For finishing
Finely grated lemon zest, from 1/2 lemon
Extra virgin olive oil, a few drops per plate
Freshly ground black pepper, to taste
Flat leaf parsley leaves, small, 8 to 12
Preparation
Step 1
Clean and score the calamari. Separate the tentacles from the bodies, pull out the quill and the innards, and rinse quickly under cold water without soaking. Slit each body open flat and lay it inside face up, then score it lightly on the diagonal at intervals of about a quarter inch, cutting no more than halfway through. Cut the scored sheets into wide bands and halve the tentacle clusters. Dry every piece thoroughly on paper. The scoring is what makes the calamari curl and take colour, and wet calamari steams instead of searing.
Step 2
Prepare the red prawns. Twist off the heads and set them aside, peel the tails leaving the last segment on, and lift out the dark intestinal tract with the point of a knife. Lay the peeled tails on a cold plate, cover them and refrigerate. These go onto the pasta raw or barely warmed, so their quality is the quality of the dish. Do not season them and do not let them sit at room temperature while you work.
Step 3
Draw the flavour out of the prawn heads. Warm 2 tablespoons of the olive oil in a small pan over low heat, add the reserved heads and press them firmly with the back of a spoon for about 3 minutes, until the oil turns deep orange and smells strongly of shellfish. Do not let the oil sizzle hard or the heads will scorch and turn bitter. Strain through a fine mesh sieve, discard the solids and set the coral oil aside. This is the step that separates a good version of this plate from a flat one.
Step 4
Build the garlic and chilli base. In a wide saute pan over low heat, warm the remaining 3 tablespoons of olive oil with the crushed garlic and the chilli. Let them infuse gently for 4 or 5 minutes until the garlic is pale gold and fragrant, never browned. Remove the cloves and take the pan off the heat before the colatura goes near it.
Step 5
Emulsify the colatura and the ink. With the pan cooled for a minute, whisk the colatura, the cuttlefish ink and the coral oil into the infused oil. Add 2 tablespoons of cold water and whisk until the mixture turns glossy and slightly thickened. Colatura loses its perfume and turns simply salty when heated, so it never cooks. Taste at this point. It should be intense and savoury with a long anchovy finish, not salt alone.
Step 6
Cook the spaghetti short of al dente. Bring the water to a rolling boil and salt it with only 1 1/2 tablespoons, half what you would normally use, because the colatura carries the rest. Add the spaghetti and cook it 2 minutes less than the package time, so it is still firm at the centre. Reserve 3/4 cup of the black starchy water before draining. That water is the working liquid for the sauce.
Step 7
Sear the calamari. While the pasta cooks, heat a heavy pan over high heat until it is genuinely hot, add the tablespoon of olive oil and lay the dried calamari in a single uncrowded layer. Leave it undisturbed for 30 seconds, turn the pieces once, and give them another 20 to 30 seconds. They should curl, mark lightly and stay opaque white with golden edges. Tip them onto a warm plate immediately. Calamari is tender below about 45 seconds of high heat and again after 40 minutes of slow braising, and rubbery in between.
Step 8
Finish the pasta off the heat. Set the pan with the colatura emulsion over the lowest possible flame, add the drained spaghetti and about half the reserved water, and toss continuously for 60 to 90 seconds, adding more water in splashes until the sauce clings to every strand. Pull it off the heat, fold in the parsley and the seared calamari, and only then lay the raw prawn tails on top so the residual warmth turns them barely opaque at the edges. Serve at once.
Plating
Warm the plates properly. Black pasta shows heat loss faster than any other, and a cold rim takes the sauce from glossy to sticky within a minute. Use wide shallow bowls heated to around 140°F (60°C), never hotter, because the raw prawns on top should stay cool at the centre.
Lift the spaghetti with a carving fork and a ladle and turn it into a tall loose nest rather than a flat pile, letting a little sauce fall around the base. Tuck the seared calamari partly into the nest so some pieces show and some disappear, and lay two red prawn tails across the top, angled rather than parallel. Finish with a few drops of olive oil, the lemon zest, a turn of black pepper and two or three small parsley leaves. Nothing else belongs on this plate.
Professional Technique
The governing technique here is the cold emulsion. Colatura is a fermented product whose aroma lives in volatile compounds that boil off in seconds, and every recipe that tells you to reduce it in a pan destroys the reason for buying it. Whisking it into warm but not hot oil with a little cold water produces a loose emulsion that carries the anchovy note intact and thickens when it meets the starch in the pasta water. The order matters: oil infused and cooled, then colatura, then ink, then water, then pasta.
The second technique is the three way split of the seafood. Calamari needs violent brief heat, red prawns need none at all, and the ink needs only to be dispersed. Cooking them together, which is what almost every version of this dish does, forces a compromise in which the prawns turn to cotton wool and the calamari goes tough. Handling each on its own terms and bringing them together in the last fifteen seconds costs nothing but organisation.
Texture and Moisture Control
The sauce is held together by starch, not by fat or cream. Squid ink spaghetti releases slightly less free starch than plain semolina pasta because the ink occupies part of the dough, so use less water than usual, around 5 quarts for 12 ounces rather than the customary 6. The result is a denser, blacker, more viscous liquid that emulsifies with the oil into something that coats each strand instead of sliding off it.
Draining 2 minutes early is not an approximation. The pasta absorbs liquid throughout the tossing stage, and a strand that leaves the pot already at al dente will be soft by the time the sauce has tightened. Add the reserved water in splashes rather than all at once, and read the pan: if the sauce looks matte and greasy the emulsion has broken and needs more water and more agitation, and if it pools thinly the starch needs another twenty seconds.
Temperature governs the prawns. Red prawns have a soft, almost creamy raw texture and a natural sweetness that heat converts into blandness, so the residual warmth of the pasta is the only cooking they get. Placed on top at the very end they firm just at the surface while the centre stays translucent.

Chef Tips
Buy colatura from Cetara and read the label for the barrel ageing, which should be at least twelve months. The industrial anchovy extracts sold beside it are thin, harsh and merely salty, and no technique recovers from them. A bottle lasts a year in a dark cupboard and gets used a teaspoon at a time.
If you cannot find true gamberi rossi, use the best raw shrimp you can get and warm them for 20 seconds in the finishing pan rather than serving them raw. Farmed shrimp lack the sweetness and the soft texture that justify the raw treatment.
Make your own ink pasta if you have the time. Semola rimacinata with cuttlefish ink worked into the water gives a flavour dried pasta cannot reach, and it cooks in about 3 minutes. If you use dried, buy a brand that lists ink rather than squid ink flavouring.
Taste the emulsion before the pasta goes near it, and correct it with water rather than salt. Colatura varies between producers, and a version that needs 2 tablespoons one week can need 3 the next. Salt is the one thing you will never add to this dish.
Common Mistakes
Cooking the colatura. Heat drives off the volatile aromatics that took a year in a chestnut barrel to develop, leaving a sauce that is salty and one dimensional. The pan comes off the heat before the colatura goes in, and it never returns to more than the barest warmth afterwards.
Salting the pasta water normally. Between the colatura and the seafood, a conventionally salted pot makes the finished plate inedible. Use half the salt you would use for any other pasta and trust the anchovy to do the rest.
Searing calamari in a crowded pan. Too many pieces at once drops the pan temperature and the calamari releases water and poaches in it, coming out pale and rubbery. Work in two batches in a genuinely hot pan.
Cooking the red prawns. Gamberi rossi lose their sweetness and their soft texture the moment they are properly cooked, turning into ordinary shrimp. They go on at the end and the pasta warms them, nothing more.
Throwing away the prawn heads. The heads hold most of the flavour, and three minutes of gentle pressing in warm oil gives a coral coloured oil that carries the whole dish.
Adding cheese. Pecorino or parmigiano on a plate already carrying fermented anchovy and cuttlefish ink produces a muddled, aggressive result. Here the rule against cheese on seafood pasta is founded on taste rather than habit.
Wine Pairing
Fiano di Avellino DOCG: The most complete match on the list. Fiano has weight and a waxy, almost oily texture that stands up to the olive oil emulsion, while its hazelnut and smoke notes meet the toasted edges of the seared calamari. The acidity is firm without being sharp, which matters when the plate already carries a heavy load of salt.
Greco di Tufo DOCG: Grown on sulphurous volcanic soils inland from Naples, this is the more mineral and more assertive Campanian white. Its sharp stone fruit and flinty finish cut straight through the anchovy depth, and the slight tannic grip that Greco develops handles the bitterness of the ink better than a softer wine would.
Falanghina del Sannio DOC: The everyday choice along this coast and a very direct one. Bright green apple and citrus acidity resets the palate between forkfuls, and the modest alcohol keeps the salt from feeling heavier than it is. Serve it cold, around 46°F (8°C).
Lacryma Christi del Vesuvio DOC: Vines planted on the black volcanic ash of Vesuvius give a white with a saline, almost smoky character that echoes the ink rather than fighting it. It is rounder than Greco and drier in impression than Falanghina, and the faint sensation of ash on the finish is an exact match for squid ink pasta.
Etna Bianco DOC: Carricante grown at altitude on the volcano gives razor sharp acidity, a lemon and green almond profile and a long salty finish. It is the best bottle here for the raw red prawns, because its cold precision throws their sweetness into relief instead of covering it.
Storage & Reheating
This is not a dish to make ahead, and a plated portion does not survive storage. The pasta absorbs the remaining sauce within minutes, the calamari firms as it cools, and the raw prawns must be eaten the day they are bought.
The components keep separately. The coral oil holds in a sealed jar in the refrigerator for 2 days and should be brought back to room temperature before use. Cleaned raw calamari keeps covered and cold for 24 hours and freezes well for up to 2 months, in fact improving slightly in tenderness. Colatura needs no refrigeration and keeps for at least a year in a cool dark cupboard.
If you must reheat leftover pasta, put it in a nonstick pan over low heat with 2 tablespoons of water, cover, and warm it for about 90 seconds, tossing once. Never use a microwave, which cooks the seafood a second time, and never add more oil, which breaks the remains of the emulsion. Lift the prawns out before reheating.
