Directions
Make the tomato jam: In a small saucepan, heat the olive oil over medium heat. Add the tomato paste and cook until lightly caramelized, 8 to 10 minutes. Add the shallots and cook until softened, 3 to 4 minutes. Add the tomatoes and cook until broken down, 15 minutes. Add the remaining ingredients and bring to a simmer. Cook until the sauce has reduced and thickened, 25 to 30 minutes, makes ½ cup. Set aside.
Make the snapper: In a medium saucepan, heat 2 inches of canola oil to 350º and line a plate with paper towels. Meanwhile, in a medium bowl, whisk together the all-purpose flour, cornstarch, baking powder and salt to incorporate. Whisk in the club soda until a smooth batter is formed.
Dip the pieces of fish into the batter and gently place into the hot oil. Fry until golden and cooked through, 1 to 2 minutes, then transfer to the prepared plate to drain. Season with salt.
Assemble the banh mi: Spread half of the tomato jam on the bottom and half of the mayonnaise on the top of each baguette. Layer 4 pieces of fish on each bottom, then divide the watercress over top. Garnish with a pinch of pickled daikon, pickled carrots, red cabbage, green cabbage, cucumber, red onion, jalapeños and cilantro leaves. Place the top halves of each baguette on and slice each sandwich into 4 pieces, then serve.
