Ingredients
 

  • 2 medium-sized fish bangus, tilapia, or mackerel, cleaned
  • 1 small onion chopped
  • 3 cloves garlic peeled and minced
  • 2 medium tomatoes chopped
  • 2-3 cups water
  • 2-3 eggs lightly beaten
  • ½ teaspoon freshly ground black pepper
  • Patis fish sauce to taste
  • Salt for seasoning fish
  • Cooking oil for frying
  • 2 tablespoons green onions chopped (for garnish)

Instructions
 

  • Season your cleaned fish generously with salt on both sides and let it sit for 5 minutes while you heat cooking oil in your wok over medium-high heat.
  • Fry the seasoned fish until golden brown and crispy on both sides, about 4-5 minutes per side depending on thickness. The skin should be beautifully crisp and the flesh should flake easily when tested with a fork.
  • Remove the fried fish from oil and drain thoroughly on paper towels, setting aside while you prepare the sauce. This step is crucial for maintaining the fish's crispy texture.
  • In your saucepan over medium heat, sauté the minced garlic until fragrant and lightly golden, about 1 minute, being careful not to burn it as this will make the sauce bitter.
  • Add the chopped onions to the garlic and cook until they become translucent and soft, approximately 3-4 minutes, stirring occasionally to prevent sticking.
  • Incorporate the chopped tomatoes and cook until they break down and become soft and saucy, about 5-7 minutes. You want them to release their juices and create a rich base.
  • Pour in the water and season with patis and freshly ground black pepper, adjusting the saltiness to your preference. Bring this mixture to a rolling boil.
  • Once boiling, slowly drizzle in the beaten eggs while gently stirring the sauce in a circular motion. This creates beautiful egg ribbons throughout the sauce rather than scrambled chunks.
  • Continue simmering until the eggs are fully cooked and evenly distributed throughout the sauce, about 2-3 minutes. The sauce should have a lovely orange-red color from the tomatoes and eggs.
  • Gently add the fried fish back to the saucepan and simmer for 3-5 minutes, allowing the flavors to meld together while being careful not to break the fish apart.
  • Transfer the fish to your serving platter and generously ladle the tomato-egg sauce over the top, ensuring every piece is well-coated with the flavorful sauce.
  • Finish with a sprinkle of freshly chopped green onions for color and a mild onion bite that complements the rich sauce perfectly.

Tips from Lola's Kitchen

  • Always pat fish completely dry before seasoning - this prevents oil splatter and ensures better browning
  • Don't skip the resting time after salting fish; it helps firm up the flesh and prevents breaking during frying
  • Use day-old eggs for better ribbons in the sauce - they hold together better than super fresh ones
  • Add a pinch of sugar if your tomatoes are too acidic - it balances the flavors beautifully
  • Test oil temperature with a small piece of garlic - it should sizzle immediately when ready
  • Keep fried fish warm in a low oven if making multiple batches
