Molho de Escabeche Português (Portuguese Pickling Sauce for Fried Fish)

My father used to come home from the market in Braganca with a paper sack of small fish, carapau usually, fry them hard and fast in a battered pan, and then drown the whole plate in a hot vinegar and onion sauce that he’d let sit until the next day before anyone was allowed to touch it.

That waiting was the hardest part of being a kid in that kitchen. Escabeche is an old preservation trick dressed up as a delicacy: fry the fish, pour a hot vinegar-onion-carrot sauce over it while everything is still warm, and let the acid do slow, quiet work overnight.

It is a completely different animal from the grilled sardines I already have on the site (the sardinhas assadas recipe, if you want the summer cookout version), because escabeche wants fried fish, not charred, and it wants to sit and mellow rather than come straight off the fire. The sauce itself is the star here and it works on more than fish. Fried vegetables, hard-boiled eggs, even leftover roast chicken all take well to a good escabeche bath.

I make a double batch whenever I have carapau or mackerel on hand, because the sauce keeps in the fridge far longer than the fish will, and having it ready means dinner is basically done the moment something hits hot oil.

Molho de Escabeche Recipe

Prep time: 10 minutes · Cook time: 10 minutes · Total: 20 minutes active (plus 4 hours marinating) · Servings: about 2 cups, enough for 2 lbs fried fish · Calories: ~90 per 2-tablespoon serving per serving

Ingredients

• 1/2 cup olive oil
• 2 large yellow onions, thinly sliced
• 4 garlic cloves, thinly sliced
• 2 carrots, thinly sliced into rounds
• 2 bay leaves
• 1 teaspoon sweet paprika
• 1/2 teaspoon whole black peppercorns
• 3/4 cup white wine vinegar
• 1/4 cup dry white wine
• Salt, to taste
• 2 lbs freshly fried fish (carapau, mackerel, sardines or smelts), for serving

Instructions

1. Heat the olive oil in a saucepan over medium heat and add the onion, garlic and carrot. Cook gently, stirring often, until soft and just turning golden at the edges, about 8 minutes; you do not want deep browning here.
2. Add the bay leaves, paprika and peppercorns and stir for 30 seconds until fragrant.
3. Pour in the vinegar and wine, add a good pinch of salt, and bring to a simmer. Let it bubble gently for 5 minutes so the vinegar loses some of its sharp edge.
4. Fry your fish separately until golden and cooked through, then arrange in a single layer in a glass or ceramic dish.
5. Pour the hot escabeche sauce evenly over the warm fish, making sure the onions and carrots settle over the top.
6. Let cool to room temperature, then cover and refrigerate at least 4 hours, ideally overnight, before serving cold or at room temperature.

Recipe Notes

• This sauce is built for small, bony pan-fried fish like carapau or smelts, which hold up to the acid better than delicate fillets.
• Do not use your best olive oil here; a good everyday oil is traditional since so much of it ends up as marinade rather than a finishing drizzle.
• The sauce keeps in the fridge up to 5 days on its own, so make a batch ahead and fry fish fresh whenever you want it.
• Leftover escabeche sauce is excellent spooned over fried zucchini, eggplant or hard-boiled eggs if you want a meatless version.
