📝 About This Recipe

A true jewel of Portuguese gastronomy, Lampreia à Bordalesa is a seasonal delicacy hailing from the Minho and Mondego rivers. This ancient dish features the prehistoric lamprey slow-braised in a rich, velvety sauce made from its own blood and full-bodied red wine. It is a complex, deep, and earthy masterpiece that represents the pinnacle of traditional Portuguese river-fish cookery.

🥗 Ingredients

The Lamprey and Marinade

  • 1 large Fresh Lamprey (approximately 1.5-2kg, must be very fresh)
  • 750 ml Red Wine (a high-quality, full-bodied dry red from the Douro or Dão region)
  • 2 tablespoons Wine Vinegar (to stabilize the blood)
  • 6 pieces Garlic Cloves (smashed and peeled)
  • 2 pieces Bay Leaves (dried or fresh)
  • 10 pieces Black Peppercorns (slightly crushed)
  • to taste Coarse Sea Salt

The Stew Base

  • 100 ml Extra Virgin Olive Oil (Portuguese origin preferred)
  • 100 grams Smoked Bacon or Chouriço (finely diced)
  • 2 large Onions (very finely chopped)
  • 1 bunch Parsley (tied with kitchen string)
  • 2 pieces Cloves (whole)

For Serving

  • 6-8 slices White Bread (thick-cut, fried in olive oil or toasted)
  • 2 cups Long Grain Rice (to be cooked 'Arroz de Lampreia' style with the sauce)
  • 1 handful Fresh Parsley (finely chopped for garnish)

👨‍🍳 Instructions

  1. 1

    Scald the lamprey quickly in boiling water for 30 seconds, then use a knife or a rough cloth to scrape off the slime and skin impurities until the skin is smooth. Rinse thoroughly in cold water.

  2. 2

    This is the most critical step: Place the lamprey over a large bowl. Make a careful incision from the vent to the head to collect all the blood into the bowl containing the vinegar (the vinegar prevents coagulation).

  3. 3

    Remove the 'cord' (notochord) carefully by pulling it from the head end. Discard the innards, keeping only the liver if desired. Cut the lamprey into 5-6cm thick medallions.

  4. 4

    In a large ceramic or glass bowl, combine the lamprey pieces, the collected blood, red wine, smashed garlic, bay leaves, peppercorns, and salt. Cover and refrigerate for 24 hours to marinate.

  5. 5

    When ready to cook, remove the lamprey pieces from the marinade and pat them dry. Strain the marinade, reserving both the liquid (blood/wine mixture) and the aromatics (garlic/bay).

  6. 6

    In a wide, heavy-bottomed clay pot or Dutch oven, heat the olive oil over medium heat. Add the diced bacon or chouriço and fry until the fat renders and it becomes crispy.

  7. 7

    Add the finely chopped onions to the pot. Sauté slowly until they are translucent and golden, about 10-12 minutes. Do not let them burn.

  8. 8

    Add the reserved garlic and bay leaves from the marinade, along with the bunch of parsley and the cloves. Stir for 2 minutes until fragrant.

  9. 9

    Carefully pour in the strained marinade liquid. Bring to a gentle simmer and let it cook for 15 minutes to reduce slightly and mellow the raw wine flavor.

  10. 10

    Gently place the lamprey medallions into the simmering sauce. Cover the pot and cook over low heat for 25-35 minutes. The lamprey is done when the flesh is tender but still holds its shape.

  11. 11

    Once cooked, remove the lamprey pieces to a warm platter. If the sauce is too thin, increase the heat and reduce it until it coats the back of a spoon with a silky, dark chocolate-like consistency.

  12. 12

    Taste the sauce and adjust the salt. Return the lamprey to the pot to heat through for 2 minutes.

  13. 13

    While the stew finishes, fry the bread slices in olive oil until golden and crunchy. These will act as the base for the rich sauce.

💡 Chef's Tips

Cleaning the lamprey is the hardest part; if you are squeamish, ask your fishmonger to clean it but emphasize you MUST have the blood collected in wine/vinegar. Never let the sauce boil vigorously once the blood is added, as it can grain; a gentle simmer is key for a silky texture. Use the best red wine you can afford; the sauce is 80% wine, so the quality directly dictates the final flavor. If the sauce lacks depth, a small piece of dark chocolate (90% cocoa) added at the end is a secret chef's trick to enhance the 'Bordalesa' richness. Lamprey is seasonal (January to April); do not attempt this with frozen lamprey as the texture and blood quality will not be the same.

🍽️ Serving Suggestions

Serve the lamprey medallions over the fried bread slices to soak up the decadent sauce. Accompany with 'Arroz de Lampreia'—rice cooked using some of the stew's sauce and a bit of extra broth. A crisp, acidic green salad with a simple vinaigrette helps cut through the richness of the blood sauce. Pair with the same red wine used in the cooking, preferably a robust Douro Red or a mature Alentejo. Finish the meal with a light citrus-based dessert to cleanse the palate after the intense flavors of the stew.
