Whole butterflied fish grilled over mangrove wood with a spicy chile paste is Nayarit's pride. This high protein, healthy dish is a fresh, keto-friendly option perfect for family gatherings.
Butterfly the whole snapper by slicing along the backbone and opening flat; pat dry for a crisp finish.
In a blender, combine garlic, achiote paste, guajillo chiles (seeded and soaked), olive oil, salt, black pepper, and juice of 2 limes; blend until smooth.
Brush the chile paste generously over both sides of the fish, ensuring coverage especially in the thickest parts; let marinate at room temperature for 20 minutes.
Preheat your grill using medium-high heat. If using mangrove wood, allow coals to burn down to even, glowing embers for consistent heat.
Place the fish skin-side down on a greased grill basket; grill for 8–10 minutes per side, flipping only once, until the flesh turns opaque and slightly charred at the edges. Serve immediately.
