Aceitunas Aliñadas Andaluzas
Andalucía's green olives are cracked just enough to drink in garlic, cumin, oregano and sherry vinegar, then left two days until the brine turns fragrant and every bite carries the aliño.

Sardinas en escabeche belong to the Cantabrian coast, where an oily fish with a short season is lightly floured, fried and covered with a warm, sharp marinade of olive oil, wine vinegar, onion, garlic and bay. This isn't boquerones en vinagre, the raw anchovy preparation. These sardines are cooked first, and that thin coat of flour gives the escabeche something to cling to without turning the fish heavy.
The overnight rest decides the dish. Straight from the pan, the vinegar sits on the surface and tastes separate from the oil. Leave the sardines covered and cold for a full day, and the flesh firms gently while the onion, bay and vinegar settle into one clean, savoury flavour. Rush that rest and you've made fried sardines with dressing, which is pleasant enough but isn't the same thing.
Buy sardines when their skin is bright, their eyes clear and their flesh firm. If fresh ones aren't good where you're standing, properly thawed frozen sardines work. Dry them very carefully because they soften a little in freezing and spit more in the oil. Small mackerel or horse mackerel can take the same escabeche, tal como se hace allí, but the result is richer and must carry the name of that fish.
Serve them cool, not numb from the refrigerator, with bread for the onion and the sharp green-gold oil. The Margin beside this recipe says only, "Leave them alone until tomorrow." Sensible advice. Siempre sale, si lo sigues.
In fishing ports along the Cantabrian coast, frying a catch and covering it with vinegar, oil and aromatics gave households more time to eat delicate oily fish before cold storage was available. The word escabeche entered Iberian cooking through the Arabic sikbaj, a vinegar-seasoned preparation whose preserving logic became rooted across the peninsula. Coastal kitchens applied it especially well to sardines, mackerel and bonito, fish plentiful enough in season to be cooked for the days ahead.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Kitchen scale
- •Large frying pan, about 28cm
- •Fine-mesh sieve and heatproof jug
- •Shallow glass or glazed ceramic dish, about 25 x 18cm
- •Fish slice or wide spatula
- •Kitchen thermometer, optional
Instructions
- 1
Clean and dry
Rinse the sardine cavities quickly under cold water, checking that no dark innards remain along the backbone. Don't soak them. Pat the fish completely dry inside and out, season with 8g of the salt, and refrigerate for 10 minutes. Water left on the skin makes the oil spit and stops the flour forming its thin, even coat.
Ask the fishmonger to remove the heads and guts but leave the backbones in. The bones help the sardines hold together during frying and the fine side bones soften as the fish rests. - 2
Flour and fry
Spread the flour on a plate. Coat each sardine lightly, including the cavity, then shake off every loose patch. Heat the olive oil in a 28cm frying pan to about 175°C. Fry in small batches for 90 seconds to 2 minutes per side, depending on size, until the skin is pale gold and the flesh has just turned opaque at the backbone. Don't crowd the pan or cook the fish crisp. Lift each batch onto a rack or absorbent paper, then arrange the sardines snugly in a shallow non-reactive dish.

Soften the onion
Let the frying oil settle for 5 minutes, then strain it through a fine sieve into a heatproof jug. Measure 150ml into a clean pan. Add the onion, garlic, bay leaves and peppercorns. Cook over low heat for 12 to 15 minutes, stirring now and then, until the onion is soft and translucent but not brown. This escabeche wants the clean sweetness of softened onion, not the dark flavour of a long sofrito.

Finish the escabeche
Take the pan off the heat, stir in the pimentón for 10 seconds, then carefully add the wine and vinegar. Return the pan to low heat, add the remaining 2g salt, and simmer gently for 3 minutes. The brief simmer joins the oil and vinegar and takes the raw edge from the wine without boiling away the brightness.

Bathe the sardines
Pour the warm escabeche, onion and all, evenly over the sardines. Use a snug dish so the liquid reaches well up their sides. Spoon some onion between the layers if the fish must overlap. Leave the shallow dish uncovered for 30 minutes, just until it loses its fiercest heat, then cover and refrigerate. Spoon the marinade over any exposed fish once during cooling.
- 6
Rest overnight
Refrigerate the sardines for at least 12 hours and preferably 24. This rest is what turns fried fish and vinegar into escabeche, so don't shorten it. Take the dish from the refrigerator 20 minutes before serving, then lift the sardines carefully with a fish slice and spoon the softened onion and marinade over them. Serve cool with bread.
Chef Tips
- •Freshness decides sardines. Look for clear eyes, bright silver skin, red gills and firm bellies. A split, soft belly means the fish has already waited too long, and no careful frying will put it right.
- •If only frozen whole sardines are available, thaw them overnight in the refrigerator and dry them twice, inside and out. They make a sound escabeche, though the flesh will be a little softer and the skin more likely to tear.
- •No sardines worth buying? Small mackerel or horse mackerel are proper fish for escabeche too. Fillet them, fry until just opaque, and expect a meatier, richer result. It is then caballa or jurel en escabeche, not sardinas.
- •Use white wine vinegar with a clean flavour. A good cider vinegar is a sensible northern substitute and makes the marinade slightly rounder and fruitier. Distilled white vinegar is too blunt here.
- •This is a refrigerated preserve, not a shelf-stable one. Keep the sardines covered and cold, use clean utensils, and eat them within 3 days.
Advance Preparation
- •Prepare the complete dish 24 hours before serving. The sardines need at least 12 hours in the escabeche, but the flavour and texture are better after a full night.
- •The sardines keep for up to 3 days covered in the refrigerator. Bring only the amount you plan to serve out for 20 minutes, leaving the rest properly chilled.
