Ingredients

• 1 cup apple cider
• 2 Golden Delicious apples, peeled and coarsely grated
• 3 medium shallots (or 1 small red onion), finely chopped
• 3 tablespoons apple cider vinegar
• 1 tablespoon curry powder
• Kosher salt and freshly ground pepper
• 1/4 cup finely chopped cilantro, plus whole leaves for topping
• 1 1/4 pounds skinless salmon fillet, cut into 1-inch chunks
• 1/2 cup panko breadcrumbs
• 2 tablespoons mayonnaise, plus more for topping
• 2 teaspoons unsalted butter, plus more for the buns
• 4 potato buns, split and toasted
• Potato chips, for serving (optional)

Instructions

1. Combine the cider, apples, 2 shallots, 2 tablespoons vinegar, 1 teaspoon curry powder, and salt and pepper to taste in a saucepan and bring to a boil. Cook until the liquid evaporates, about 12 minutes; let cool slightly. Stir in 2 tablespoons chopped cilantro.
2. Meanwhile, pulse three-quarters of the salmon in a food processor until finely ground. Add the remaining salmon; pulse until chopped. Transfer to a bowl; stir in the panko, mayonnaise and the remaining shallot, 2 tablespoons cilantro, 1 tablespoon vinegar and 2 teaspoons curry powder. Add salt and pepper. Form into four 1/2-inch-thick patties.
3. Melt the butter in a large nonstick skillet over medium-high heat. Add the patties and cook until browned and cooked through, 2 to 3 minutes per side. Butter the buns and sandwich with the salmon burgers, mayonnaise, the apple relish and more cilantro. Serve with chips.
