Ingredients

  • •1 lb Desalted Portuguese bacalhau (salt cod), poached and shredded
  • •1 lb Yukon gold potatoes, cut into paper-thin matchsticks (batata palha) and crisp-fried
  • •6 large Farm fresh eggs, lightly beaten with salt and white pepper
  • •2 medium Yellow onions, sliced into thin crescents
  • •4 cloves Garlic, thinly sliced
  • •1/3 cup Portuguese extra virgin olive oil

  • •1/3 cup Small Portuguese black olives (azeitonas galega)
  • •1/4 cup Fresh flat-leaf parsley, finely chopped
  • •1 tbsp High-grade finishing Portuguese olive oil

Step-by-Step Instructions

PREPARATION & METHOD

1
Step 1: Desalt & Flake Cod

Soak dried salt cod in cold refrigerated water for 48 hours, changing water twice daily. Poach gently in simmering water for 8 minutes, discard skin and bones, and flake the tender cod into delicate bite-sized shreds.

2
Step 2: Sweat Aromatics in Rich Olive Oil

Warm extra virgin olive oil in a wide heavy skillet over medium-low heat. Sweat sliced onions and garlic slowly for 12-15 minutes until soft, translucent, and sweet without developing color.

3
Step 3: Fold Flaked Cod & Crisp Straw Potatoes

Increase heat slightly, add shredded cod to the onions, and toss for 3 minutes to coat in olive oil. Fold in crisp matchstick potatoes gently so they absorb savory aromatics while maintaining structural crispness.

4
Step 4: Gentle Egg Custard Fold & Garnish

Pull skillet off direct flame. Pour in beaten eggs, stirring constantly with a rubber spatula in residual pan heat for 60 seconds until a creamy, glossy custard forms (never dry). Scatter black olives and chopped parsley over top.

Beverage Pairing

Portuguese Vinho Verde or Crisp Encruzado Dão White

A chilled, spritzy Vinho Verde provides vibrant acidity that cuts through rich olive oil and creamy egg curds, elevating the tender flaked cod.

Culinary Science Insight

Residual Heat Coagulation & Texture Contrast

Off-heat folding prevents egg protein ovalbumin from seizing past 155°F, creating a luscious glossy ribbon that binds crisp potato starch without releasing weeping syneresis liquid.
