📋 Step-by-Step Guide (6 Steps)
Scale and Gut the Fish
Hold the fish firmly by the tail over a sink or cutting board. Scrape firmly from tail to head using a scaler or spoon to remove all scales. Cut along the belly line from vent to gills, remove the entrails, and rinse the cavity thoroughly under cold running water.
- • Fish skin is smooth with no translucent loose scales visible.
- • Abdominal cavity is clean with dark kidney membrane scrubbed out under spine.
- • Missing scales around the collar and fin bases.
- • Puncturing the bitter gall bladder during gutting.
Score and Dry the Fish
Cut 3 to 4 diagonal slits on both sides of the fish down to the backbone, spaced about an inch apart. Pat the entire exterior and inside of the belly cavity thoroughly with paper towels until completely dry.
- • Clean diagonal cut lines showing white flesh through skin.
- • Matte skin surface with zero liquid sheen or pooling.
- • Cutting all the way through the backbone.
- • Leaving moisture in the belly cavity.
Season and Dust with Starch
Sprinkle a pinch of salt over both sides and inside the cavity. Dust the fish lightly with cornstarch or rice flour, making sure to get inside the cuts, then vigorously shake off all excess powder.
- • Ultra-thin translucent veil of starch coating the skin.
- • No clumps of dry white powder inside the slits.
- • Applying a thick batter-like layer of starch.
- • Leaving clumps inside the scored slits.
Fry the Fish Until Crisp
Heat 1 to 2 inches of oil in a wok to 350-375°F (175-190°C). Gently slide the fish in away from you; fry undisturbed for 5-7 minutes until the bottom is deeply golden, then carefully flip once and fry the second side for another 4-5 minutes until rigid and crisp.
- • Entire skin is deep golden brown and scores have curled open crisply.
- • Fish holds its shape stiffly when lifted with a strainer.
- • Flipping too early while the skin is still sticking to the pan.
- • Oil temperature too low, causing greasy, soggy fish.
Prepare and Simmer the Spicy Sauce
Drain wok, leaving 1 tablespoon of oil over medium heat. Sauté minced garlic and chilies for 30 seconds until fragrant, then add fish sauce, soy sauce, sugar, and a splash of water. Simmer for 1-2 minutes until slightly thickened into a glossy syrup, then finish with lime juice off the heat.
- • Garlic and chilies are tender and suspended in an amber, bubbling glaze.
- • Sauce coats the back of a spoon with a slight syrupy consistency.
- • Burning the minced garlic over high heat.
- • Boiling after adding lime juice, which causes bitterness.
Plate and Spoon Sauce
Transfer the fried whole fish onto an oval serving platter. Pour or spoon the hot spicy chili glaze directly over the center cuts of the fish, letting excess sauce pool on the plate so the outer edges stay crunchy.
- • Red and green chili chunks glistening over golden scored fish meat.
- • Sauce pooling slightly on the bottom of the platter with head and tail remaining crisp.
- • Completely submerging the fish in sauce, making the crust soggy immediately.
- • Plating on a paper towel and letting sauce soak into paper.
