Fried Fish Sandwich with Pepper Slaw recipe | Epicurious.com

PreparationMake the slaw: Combine lemon and lime juice, hot sauce, olive oil, oregano, and salt in a large bowl. Add onion, jalapeño, and poblano chile and toss to combine. Let marinate at least 30 minutes and up to 1 hour while you prepare the rest of the dish. Make the tartar sauce: Combine cornichons, mayonnaise, parsley, capers, tomato powder (if using), vinegar, chili powder, and salt in a small bowl. Make the fish: Whisk flour, cornstarch, oregano, onion powder, tomato powder (if using), garlic powder, and 3 tsp. salt in a large bowl. Add club soda and quickly whisk to incorporate. Pour canola oil into a large skillet to a depth of 1/4". Heat oil over medium-high until shimmering, hot, and an instant-read thermometer registers 350°F. Dip fish into batter to coat, shake off excess, then fry until golden, crispy, and cooked through, about 4 minutes per side. Work in batches if necessary and adjust the heat as needed to keep oil at 350°F. Transfer to paper towels and season with salt. Assemble the sandwiches: Strain the slaw and discard liquid. Transfer slaw to a medium bowl. Spread 1 Tbsp. tartar sauce on both sides of each bun and place tomato slices on bottom halves. Divide fried fish and slaw among sandwiches and add top halves of buns.
