Ingredients

• For the Fish & Marinade:
• 1.5 lbs (about 680g) firm white fish fillets, such as snapper, cod, mahi-mahi, or halibut, skinless or skin-on, cut into 1.5-inch thick pieces
• 3 large limes, 2 juiced (about 1/4 cup), 1 cut into wedges for serving
• 4 cloves garlic, minced or pressed
• 1 teaspoon sea salt, plus more to taste
• 1/2 teaspoon black pepper
• 2 scallions (green onions), thinly sliced (white and green parts separated)
• 1-2 fresh green chili peppers (e.g., habanero or Scotch bonnet for heat, or a milder jalapeño/serrano for less spice), left whole or sliced for more heat
• For the Broth:
• 1 tablespoon neutral oil (optional, for sweating aromatics)
• 1 medium yellow onion, finely diced
• 2 cloves garlic, minced
• 4 cups water or light fish stock
• 2 sprigs fresh thyme
• 2-3 whole cloves
• 3-4 allspice berries (or 1/4 teaspoon ground allspice + 1 bay leaf)
• 1/4 cup fresh parsley, chopped, plus more for garnish

Directions

1. Prep the Fish: Gently rinse your fresh fish fillets under cold water and pat them thoroughly dry with paper towels. Cut the fish into roughly 1.5-inch thick pieces. This size helps them poach evenly without falling apart.
2. Quick Lime Marinade: In a medium bowl, combine the fresh lime juice, minced garlic, 1 teaspoon salt, 1/2 teaspoon black pepper, and the white parts of the sliced scallions. If using, add the whole or sliced chili pepper(s) to this mixture. Add the fish pieces, ensuring they are coated well. Toss gently. Let the fish marinate for no more than 10-15 minutes at room temperature. Marinating too long can "cook" the fish with the acid, changing its texture.
3. Build the Broth: Heat the optional neutral oil in a medium pot or Dutch oven over medium heat. Add the diced yellow onion and cook until softened and translucent, about 5-7 minutes. Add the remaining minced garlic and cook for another minute until fragrant. Pour in the water or fish stock. Add the fresh thyme sprigs, whole cloves, and allspice berries (or ground allspice and bay leaf). Bring the broth to a gentle simmer. Taste and adjust salt as needed – remember, the fish marinade also has salt.
4. Poach the Fish: Once the broth is gently simmering, carefully add the marinated fish pieces and the marinade liquid (including the chili) to the pot. Ensure the fish is submerged. Keep the heat at a gentle simmer; do not boil vigorously. Poach the fish for 5-8 minutes, depending on its thickness. The fish is done when it flakes easily with a fork and is opaque throughout. Overcooking will make it dry and tough.
5. Finish and Serve: Remove the pot from the heat. Carefully remove the thyme sprigs, whole cloves, and allspice berries (if used). Stir in the chopped fresh parsley and the green parts of the sliced scallions. Give it a final squeeze of fresh lime juice from a wedge for an extra burst of brightness. Ladle the seafood stew recipe into bowls, ensuring each serving gets some fish, broth, and aromatics. Serve immediately with extra lime wedges on the side.
