📋 Step-by-Step Guide (6 Steps)
Prepare and Score the Fish
Pat the pre-cleaned puffer fish completely dry using paper towels. Place the fish on a stable cutting board and make shallow diagonal scores about 1/4-inch deep along the thickest parts of the flesh to allow heat and marinade penetration.
- • Fish surface is dry and free of excess moisture
- • Even diagonal cuts visible across the thickest areas
- • Cutting too deep and slicing completely through the fillet
Mix the Spicy Glaze
In a small mixing bowl, combine chili paste, minced garlic, soy sauce, sesame oil, and honey. Whisk vigorously until the sugar is fully dissolved and the mixture forms a glossy, smooth paste.
- • Uniform, glossy red paste with no visible undissolved sugar granules
- • Leaving clumps of garlic or chili paste unmixed
Preheat and Oil the Grill
Preheat your grill to medium-high heat (approximately 375°F to 400°F). Using long-handled tongs and a folded paper towel dipped in vegetable oil, wipe the grill grates thoroughly to create a non-stick surface.
- • Grates are shiny and lightly smoking
- • Heat gauge reads around 375-400°F
- • Applying too much oil, causing aggressive flare-ups
Initial Sear
Place the scored fish onto the hot grill grates over direct heat. Cook undisturbed for 3 to 4 minutes until the underside releases naturally and light grill marks form.
- • Edges of the fish turn opaque white
- • Fish releases easily from the grate without tearing
- • Trying to flip or move the fish too early while it is still adhering to the grates
Flip and Baste
Carefully flip the fish using tongs. Brush a generous layer of the spicy glaze over the seared top side, ensuring it coats into the score marks. Grill for another 3 minutes.
- • Glossy red glaze covering the entire top surface
- • Glaze beginning to bubble around the edges
- • Dipping the brush back into raw-fish-contaminated marinade bowls after touching cooked surfaces
Final Glaze and Rest
Flip once more for 30 to 60 seconds to lightly caramelize the glazed side, then remove the fish from the grill onto a clean serving plate. Let rest for 2 minutes before garnishing and serving hot.
- • Internal fish meat is opaque and flakes gently
- • Glaze has caramelized slightly charred spots
- • Overcooking until the delicate meat turns dry and rubbery
