Methods

1. Pat the fish dry with paper towels. Halve each fillet lengthwise (let the backbone indentation be your guide) and then cut each fillet half into “fish fingers” roughly 4 inches long and 1 inch wide. To obtain long pieces, you may have to cut the fish at an angle, crating trapazoid-shaped pieces. Set aside.
2. In a large bowl, combine the turmeric, ginger or galangal, anchovy paste, fish sauce, sour cream, and 2 tablespoons canola oil. Add the fish and use your hands or a silicone spatula to coat pieces evenly (insert something about hands and how to get turmeric off). Cover and set aside to marinate while you ready the other components. Set the dill, green onions, and remaining 1/4 cup canola oil near the stove.
3. To make the dipping sauce. In a small bowl, whisk together the anchovy paste, sugar, and lime juice, which will give you a pale purple mixture. Add the fish sauce and water to taste; if the sauce is a little bitter or sharp, add the vinegar, 1 teaspoon at a time. Then, add the chilies, stir, and set aside.
4. Position an oven rack about 4 inches from the broiler’s heat source and preheat the broiler for 20 minutes. Line a baking sheet with aluminium foil and set a rack inside.
5. To prep the accompaniments. In a pot of unsalted water, boil the noodles until chewy-tender; the cooking time depends on the noodle and brand. Drain, rinse with cool water and drain well for about 5 minutes. For easy serving, arrange the noodles as 2- to 3-inch nests on two plates or in low bowls. Place the noodles, lettuce, herbs, peanuts, dipping sauce, and rice crackers on the table. For each diner, set out a cereal bowl or small soup bowl, chopsticks (or a fork), and a spoon.
6. Arrange the fish pieces on the prepared rack, laying them flat, like a jigsaw puzzle. Broil for 8 minutes, until the fish is sizzling and a little brown; check after 5 minutes and rotate the pan if needed. Using chopsticks, tongs, or an offset spatula, delicately loosen and turn fish over, then broil for 5 to 8 minutes. Transfer the fish to one or two serving plates and blanket with the dill and green onions.
7. In a small saucepan, heat the remaining ¼ cup canola oil until faint wisps of smoke start rising. Pour the hot oil over the green onions and dill to sear and wilt them. Using two spoons, gently combine, and then place the fish on the table.
8. When ready to eat, diners should put some of each component in an individual bowl, tearing the lettuce and herbs into bite-sized pieces and breaking up the rice crackers. Dress with a small drizzle of sauce (wield chopsticks and spoon to mix) and gobble it up. Repeat until everything is gone.
