Fried-Fish Sandwiches With Jalapeño-Spiked Tomatoes

Ingredients

• 2 cups all-purpose flour
• salt
• 2 1/4 cups club soda
• 1 teaspoon ground cumin
• 1 teaspoon dried oregano
• 1 teaspoon hot paprika

• 4 (6 ounce)  skinless haddock or hake fillets
• fresh ground pepper
• 2 medium tomatoes, thinly sliced
• 1 small yellow onion, thinly sliced
• 1 jalapeno, seeded and thinly sliced
• 1/4 cup cilantro, coarsely chopped
• vegetable oil, for frying
• 4 kaiser rolls, split and toasted
• 4 large boston lettuce leaves

Directions

1. 1

   Fill a large bowl with ice water. In a medium bowl, whisk 2 cups of the flour with 1 teaspoon of salt. Whisk in the club soda until the batter is smooth. Set the bowl in the ice bath; let stand until chilled, 10 minutes.

2. 2

   Meanwhile, in a small bowl, combine the cumin with the oregano and paprika. Season the fish with salt and pepper and sprinkle with the spice mixture. In a large bowl, gently toss the tomatoes with the onion, jalapeño and cilantro and season with salt.

3. 3

   In a large, deep skillet, heat 2 inches of vegetable oil to 350°. Place a rack over a rimmed baking sheet. Working with two at a time, dredge the fish fillets in the flour, shaking off any excess. Dip the fillets in the batter and fry, turning once, until golden and cooked through, 4 minutes; transfer to the rack. Repeat with the remaining fish.

4. 4

   Arrange the rolls on a work surface cut sides up. Top the bottom halves with the lettuce, fried fish and tomato mixture. Close the sandwiches and serve right away.
