Vietnamese caramel sauce (nước màu) is a transformative condiment: sugar cooked to a deep amber, then shocked with fish sauce, creating something savory, sweet, bitter, and umami all at once. Wild Alaskan sablefish, with its naturally high oil content, stands up to this bold sauce and stays melt-in-your-mouth tender. This dish is keto-friendly, gluten-free, and dairy-free.

Ingredients

• 4 wild Alaskan sablefish portions (5–6 oz each), thawed
• 1 tablespoon neutral oil (avocado or grapeseed)
• Salt and pepper to taste
• Vietnamese Caramel Sauce:
• ¼ cup granulated sugar
• 2 tablespoons water
• 3 tablespoons fish sauce
• 1 tablespoon fresh lime juice
• 1-inch piece fresh ginger, minced
• 3 cloves garlic, minced
• 1 small shallot, thinly sliced
• ½ teaspoon crushed red pepper flakes (optional)
• Garnish: Fresh cilantro, sliced scallions, lime wedges

Instructions

1. Make Caramel: In a small saucepan, combine sugar and water over medium heat. Swirl (don't stir) until sugar dissolves, then cook until it turns deep amber, about 4–5 minutes. Remove from heat.
2. Add Fish Sauce: Carefully add fish sauce (it will sputter). Return to low heat and stir until smooth. Add lime juice, ginger, garlic, shallot, and red pepper flakes. Simmer 2 minutes. Set aside.
3. Sear Sablefish: Pat portions dry and season with salt and pepper. Heat oil in a nonstick skillet over medium-high heat. Sear skin-side down for 3–4 minutes until crispy. Flip and cook 2–3 minutes more.
4. Glaze: Pour caramel sauce into the skillet. Spoon sauce over the fish and cook 1–2 minutes until fish is glazed and cooked through (145°F).
5. Serve: Transfer to plates, spoon remaining sauce over the top. Garnish with cilantro, scallions, and lime wedges. Serve with steamed jasmine rice.
