Set your stove to medium heat (190°C/375°F) and gather all your ingredients and equipment on the counter.
Wash the dulong (silverfish) in cold water using a fine-mesh strainer. Drain well and pat dry with paper towels. This removes excess moisture and helps achieve crispy edges.
Break two room-temperature eggs into a medium mixing bowl and beat them lightly until yolks and whites combine.
Add one tablespoon of flour and two teaspoons of cornstarch to your beaten eggs. Whisk until smooth with no lumps.
Gently fold your dried dulong into the egg mixture. Be gentle to avoid breaking the delicate fish. Season with salt and black pepper to taste.
Let this mixture rest for 5 minutes - this helps the flour work better with the eggs.
Heat two tablespoons of oil in your non-stick pan. You'll know it's ready when the oil shimmers but isn't smoking.
Using a ⅓ cup measure, carefully pour portions of your mixture into the hot pan. Keep about 2 inches space between each portion if cooking multiple pieces.
Cook for 3-4 minutes until the bottom turns golden brown and edges become crispy.
Flip each piece carefully using a wide spatula. Cook another 2-3 minutes until both sides are golden brown.
Place your cooked torta on a paper-towel-lined plate to remove extra oil.
Serve immediately while hot with steaming white rice and your choice of dipping sauce - either spiced vinegar or sweet chili sauce.
Note: For the best results, use fresh oil for each new batch, and wipe your pan clean between batches if needed.
The perfect Tortang Dulong should be golden brown outside, moist inside, with crispy lacy edges and easily cut with a fork.
