Squid in its own ink: Basque vs. Catalan version
Squid in its own ink is a dish with deep roots in northern Spanish cuisine, but there is no single canonical recipe. The two great traditions, Basque and Catalan, produce markedly distinct results that reflect the culinary personality of each region.
The Basque version is the most widely known and replicated. It is based on a long sofrito of onion, sautéed until caramelized, to which tomato, white wine, and ink dissolved in fish broth are added. The onion, slow-cooked for 20-30 minutes, is the soul of the Basque dish: it provides a natural sweetness that balances the intense marine flavor of the ink. The result is a black, dense, and silky sauce with a deep and complex flavor.
The Catalan version, known as calamars amb la seva tinta, tends to be more direct and seafood-focused. It uses less onion, incorporates a more pronounced tomato sofrito, and in some regions, adds picada (a paste of almonds, garlic, parsley, and cracker) at the end of cooking to thicken and flavor the sauce. The result is a sauce with more texture and a nutty touch that distinguishes it from the Basque version's smoothness.
Both versions are extraordinary, and the choice is a matter of personal taste. The recipe we develop below follows the Basque tradition, the most widespread, but we include notes for those who wish to explore the Catalan variant.
Baby squid, squid, and flying squid: differences
One of the most frequent points of confusion is the difference between the various cephalopods used in this recipe. Not all are the same, and the choice of product directly affects the dish's outcome.
| Characteristic | Baby Squid (Chipirones) | Squid (Calamares) | Flying Squid (Pota) |
|---|---|---|---|
| Size | 5-12 cm (small) | 15-40 cm (medium to large) | 20-60 cm (large) |
| Texture | Very tender, delicate | Firm, softens with slow cooking | Harder, fibrous |
| Flavor | Mild, sweet, marine | More pronounced, iodized | Less refined, more neutral |
| Own ink | Small amount (very small sac) | Moderate amount | Generous amount |
| Approx. price | 12-20 EUR/kg | 8-14 EUR/kg | 4-7 EUR/kg |
| Best use in ink | Whole, elegant presentation | In rings, most versatile | Chopped, for economical stews |
| Cooking time needed | 20-30 minutes | 30-45 minutes | 45-60 minutes minimum |
Baby squid (chipirones) are the premium option: young, tender, and with a spectacular presentation when served whole bathed in the black sauce. Medium-sized squid (calamares) are the most practical option with the best quality-price ratio. Flying squid (pota) is the economical alternative, but it requires longer cooking to soften, and its flavor is less refined. Avoid substituting flying squid for squid if you are looking for a gourmet result.
How to clean squid step-by-step
Cleaning fresh squid intimidates many cooks, but it is a logical and quick process once you master it. With a couple of attempts, it becomes routine.
- Separate the head from the body: hold the body with one hand and gently pull the head and tentacles with the other. The entrails will come out attached to the head in a single movement.
- Locate and reserve the ink sac: among the entrails, you will find a small, elongated, silvery sac. This is the ink sac. Carefully remove it and place it in a small glass with a tablespoon of water. If it breaks during extraction, collect as much ink as possible with a spoon.
- Remove the quill: insert your fingers into the body and locate the quill, a transparent, elongated cartilage that acts as an internal skeleton. Pull it out and discard it.
- Clean the inside of the body: remove any remaining entrails from the inside. Rinse under cold running water. If you wish, you can also remove the purplish outer skin, although this is optional, and many cooks leave it because it adds color to the sauce.
- Prepare the tentacles: cut the head just below the eyes. The tentacles are fully utilized and added to the stew. Discard the eyes and the beak (a hard, round piece in the center of the tentacles).
- Cut according to size: if the squid are large, cut the body into rings 1-1.5 cm thick. If they are baby squid, leave them whole or at most cut them in half. The tentacles are left whole.

Squid ink: what it is and where to buy it
Squid ink is a natural pigment that the animal uses as a defense mechanism: it expels it to create a dark cloud that confuses predators while it escapes. From a culinary point of view, it is an extraordinary ingredient with an intense marine flavor, slightly salty, and with umami notes that cannot be achieved with any other ingredient.
Ink is mainly composed of melanin, mucopolysaccharides, and small amounts of minerals like iron and copper. It is completely safe for consumption and, in fact, has documented antioxidant and antimicrobial properties.
For squid in its own ink, you will need more ink than a single squid provides. The solution is to buy squid ink sachets, available in most fishmongers (ask the fishmonger directly), in the frozen section of well-stocked supermarkets, and in online food stores. They come in 4-gram sachets that are inexpensive and go a long way. Estimate 2-3 sachets for 4 people, in addition to the squid's own ink.
Ingredients for squid in its own ink
This recipe serves 4 people as a main course. It is a generous stew that pairs perfectly with white rice or good bread.
- 800 g fresh squid (or baby squid if you find small ones)
- 2 medium onions, finely chopped
- 3 cloves garlic, minced
- 1 large ripe tomato, grated
- Squid ink: the squid's own ink + 2-3 extra sachets
- 150 ml dry white wine
- 200 ml fish stock or fumet
- 4 tablespoons extra virgin olive oil
- Salt and black pepper
- 1 teaspoon sugar (optional, to counteract the bitterness of the ink)
- Fresh chopped parsley (for serving)
Step-by-step recipe: squid in its own ink
- Sauté the onion patiently: heat the oil in a wide, shallow pot. Add the finely chopped onion and cook over medium-low heat for 15-20 minutes, stirring every few minutes, until it is completely transparent, soft, and slightly sweet. This step cannot be rushed: a well-sautéed onion is the foundation of the entire dish's flavor.
- Add garlic and tomato: slightly increase the heat, add the minced garlic and cook for 1 minute until fragrant. Add the grated tomato and cook for 5-6 more minutes until it evaporates its water and darkens in color.
- Sear the squid: increase the heat to medium-high. Add the squid rings and tentacles and sauté for 2-3 minutes, stirring until they change color and lose their translucent appearance. Do not cook them further at this stage, or they will become rubbery.
- Deglaze with white wine: pour the wine over the squid and let the alcohol evaporate for 2 minutes, scraping the bottom of the pot with a wooden spoon to release any stuck-on flavors.
- Incorporate the ink: in a small bowl, dissolve the reserved squid ink along with the extra sachets in the warm fish stock. Mix well until you get a homogeneous black liquid and pour it into the pot. Stir to combine.
- Simmer over low heat: reduce the heat to minimum, cover the pot, and cook for 30-40 minutes. The squid needs this time to tenderize completely. Stir every 10 minutes to prevent sticking to the bottom and check that the sauce maintains a consistency that is neither too thin nor too thick.
- Adjust salt and texture: taste and adjust salt. If the ink leaves a bitter note, add half a teaspoon of sugar. If the sauce is too thin, uncover and increase the heat for 5 minutes. If it is too thick, add a little more stock.
- Rest and serve: like most stews, squid in its own ink improves with resting. Ideally, prepare it the day before and gently reheat it the next day. Serve with fresh chopped parsley on top and accompanied by white rice or crusty bread. This dish is reminiscent of grand fish zarzuelas in its depth of flavor.
Squid in its own ink with rice
The most classic accompaniment for squid in its own ink is white rice. The black sauce soaks into the rice, creating a spectacular visual contrast and an addictive flavor that utilizes every drop of the stew.
The most traditional way in the Basque Country is to serve the stew on one side of the plate and a mound of white rice on the other, allowing the diner to mix according to their preferences. This presentation allows you to appreciate the squid and the sauce separately before combining them.
For a more integrated version, you can prepare black rice by cooking the rice directly in the ink sauce. When the stew has cooked for 20 minutes, add 300 grams of bomba rice along with additional broth (double the volume of the rice) and cook for 18-20 more minutes until the rice absorbs the liquid. The result is a creamy black rice with tender squid pieces that works as a main course.
The third option, the simplest and for many the best, is simply rustic bread for dipping in the sauce. A bread with a crispy crust and a fluffy crumb that soaks up that black sauce is a delight that rivals any side dish. If you enjoy experimenting with seafood dishes, combine this recipe with a fish soup as a starter.
Slow cooking vs. fast cooking
There is a recurring debate among chefs about the ideal cooking method for squid in its ink. The two approaches yield different results, and each has its proponents.
| Aspect | Slow Cooking (30-45 min) | Fast Cooking (5-8 min) |
|---|---|---|
| Heat | Low, covered | Medium-high, uncovered |
| Squid texture | Tender, almost melts | Firm, slightly elastic |
| Sauce flavor | Deep, integrated, complex | Fresher, directly seafood-like |
| Sauce consistency | Thick, unctuous | Light, more liquid |
| Best for | Large squid, pota | Very fresh and small baby squid |
| Tradition | Basque, Cantabrian | Mediterranean, modern |
| Resting | Improves significantly the next day | Best consumed immediately |
The general rule is simple: slow cooking over low heat is the safest method and produces the most consistent results. Squid goes through a rubbery phase between 3 and 20 minutes of cooking, and only softens by patiently overcoming that barrier. Fast cooking only works with very fresh and small baby squid that don't become rubbery if cooked for less than 3 minutes. If you are unsure of the size or freshness of your product, always opt for slow cooking.
Storage and freezing
Squid in its ink is a dish that freezes exceptionally well, making it an ideal preparation to make in quantity and store individual portions. Once cooked and cooled to room temperature, divide it into airtight containers or freezer bags, leaving about half an inch of space for expansion. It keeps perfectly for 2-3 months in the freezer.
To thaw, the ideal method is to transfer the container from the freezer to the refrigerator the night before and reheat the next day over low heat, stirring gently. The microwave works as a quick alternative, but be careful not to dry out the squid by heating at medium power with intervals.
In the refrigerator, the fresh stew keeps for 3-4 days without problems. Like all spoon stews, the flavor improves immensely after resting for 12-24 hours because the squid fibers absorb the sauce and the flavors integrate. Many Basque chefs deliberately prepare this dish the day before to serve it reheated the next day, when it is at its optimal point.
Canned squid in its ink
If you don't have time or prefer the convenience of opening a can, the canned baby squid in its ink from the best Spanish canneries are an alternative that won't disappoint. Galician and Basque canneries produce whole baby squid in ink sauce that rivals many homemade versions.
To choose a good preserve, look for whole baby squid (not pieces), sauce made with natural ink (not black coloring), olive oil (not sunflower), and from identifiable artisan canneries. A good can of baby squid in its ink, gently heated and served with white rice, is a luxurious dinner that can be prepared in 5 minutes.
At Bacalalo, you can find artisan gourmet preserves from the best canneries, including baby squid in its ink perfect for a quick and elegant dinner any day of the week.
Frequently Asked Questions
What is the difference between squid and baby squid?
Baby squid are young and small squid, generally between 5 and 12 centimeters. For the ink recipe, both work perfectly. Baby squid are more tender with less cooking time and can be served whole, which improves presentation. Large squid are cut into rings and need about 10-15 more minutes of stewing to soften completely.
Does squid ink stain permanently?
Squid ink stains intensely at the moment but is not permanent on most surfaces and fabrics. On clothes, a normal wash in a washing machine with soap is usually sufficient if you act relatively quickly. On countertops and cutting boards, clean splashes with soap and water immediately. Wear an apron when cooking and have a damp cloth handy to clean drops as they happen.
Can squid in its ink be frozen?
Yes, it's one of the stews that freezes best. Once cold, divide it into airtight containers or freezer bags and store it in the freezer, where it keeps perfectly for 2-3 months. To thaw, transfer it to the refrigerator the night before and reheat it over low heat. The flavor and texture remain practically intact after freezing.
Where can I buy squid ink if my squid doesn't have it?
Squid ink is sold in individual 4-gram sachets in most fishmongers, in the frozen or refrigerated section of supermarkets, and in online food stores. They are very inexpensive, costing between 0.50 and 1 euro per sachet, and go a long way. Estimate 2-3 sachets for 4 people in addition to the ink you extract from the squid itself. It's always a good idea to have some reserve sachets in the freezer.
Why is my squid rubbery?
Squid goes through an unavoidable rubbery phase between 3 and 20 minutes of cooking. If you cook it too little, it will be raw and elastic, and if you cook it in that intermediate range, it will be tough. The trick is to overcome that barrier: cook over low heat with the lid on for at least 30-40 minutes, and the squid will soften again until tender. Patience is the key to this dish.
Is squid ink healthy?
Yes, squid ink is a completely safe ingredient with interesting nutritional properties. It is rich in iron, contains antioxidants, and has documented antimicrobial properties in scientific studies. It has no known contraindications for the general population and provides a unique and irreducible umami flavor with any other ingredient. People with shellfish allergies should consult their doctor.
Can I use pota instead of squid for this recipe?
You can, but the result will be different. Pota is cheaper but has tougher meat and a less refined flavor than squid. You will need to extend the cooking time to a minimum of 45-60 minutes for it to become tender. The sauce will still be good because the ink and sofrito are the same, but the texture and flavor of the cephalopod will be notably inferior. For special occasions, it's worth investing in squid or baby squid.
What wine pairs best with squid in its ink?
A full-bodied white wine like a Godello from Bierzo or a Basque Txakolí are classic options and best complement the intensity of the ink sauce. If you prefer red, a light, unoaked young Rioja Alavesa works surprisingly well. The key is to avoid wines with a lot of tannin or extensive aging that would compete with the dish's powerful flavors. A fresh Albariño is also a safe bet.
Is it better to prepare squid in its ink the day before?
Without a doubt. Like most stews, squid in its ink improves immensely after resting for 12-24 hours in the refrigerator. During resting, the squid fibers absorb the sauce, the flavors integrate, and the texture becomes smoother. It is a common practice in Basque restaurants and a practical advantage for the home cook, as you can split the work into two days and serve a dish that tastes better with no extra effort.
How do I prevent the ink sauce from being bitter?
Bitterness in ink sauce can have two origins. The first is an excess of ink without enough broth or sofrito to balance it: adjust the proportion. The second is insufficient cooking of the onion sofrito, which has not had time to caramelize and provide natural sweetness. If, despite everything, you notice a bitter note, half a teaspoon of sugar corrects the problem without altering the dish's flavor profile.
Can this recipe be made with frozen squid?
Yes, frozen squid yields acceptable results, though inferior to fresh product. Thaw them completely in the refrigerator, drain them well, and pat them dry with paper towels before searing. Keep in mind that frozen squid releases more water during cooking, which can dilute the sauce. Compensate by adding an extra sachet of ink. Frozen squid do not come with their own ink sac, so you will rely entirely on commercial sachets.
Is squid in its ink suitable for children?
Absolutely. Squid ink is a natural and safe ingredient for children. The only obstacle is usually psychological: the intense black color can be unappealing to young children. A strategy that works is to serve it mixed with rice, where the "black rice" appearance is more familiar and appetizing. The seafood flavor, which is not excessively strong, is usually liked by children accustomed to fish. As with any seafood, introduce it with caution due to potential allergies.
