Direction :

Prepare the fish

1. Stir together water and 2 tablespoons of the kosher salt in a large bowl until salt is dissolved. Add fish; cover and refrigerate for 1 hour.

Make the tartare sauce

1. Whisk together egg yolks and mustard in a large bowl. Whisk in white wine vinegar.
2. Slowly drizzle oil, a few drops at a time, into egg yolk mixture, whisking constantly, until all oil is used. If mixture becomes too thick, add a splash of water to thin out. Whisk in lemon juice, kosher salt, and cayenne pepper.
3. Transfer 1 cup (about half) egg yolk mixture to a medium bowl; reserve remaining mixture for another use. Add gherkins, capers, shallot, tarragon, parsley, and chervil to bowl with egg yolk mixture; stir to combine. Cover and refrigerate until ready to use.

Prepare the Triple-Cooked Chips

1. Bring water to a boil in a large pot over high. Once boiling, reduce heat to a simmer over medium-low. Place a wire rack in a baking sheet, and set aside.
2. While water comes to a boil, trim and square off ends and sides of potatoes to create 4 (4- x 1 1/2-inch) rectangles. Cut each rectangle into 3 (4- x 1/2-inch) planks; stack and cut into 9 (4- x 1/2-inch) logs.
3. Add salt to simmering water in pot; add potatoes, and cook until tender but holding their shape, about 9 minutes. Remove potatoes from water using a slotted spoon or spider; place on prepared rack-lined baking sheet, and let stand until cooled and dried, about 15 minutes.
4. While potatoes dry, pour oil into a heavy saucepan, Dutch oven, or deep-fat fryer to a depth of 2 to 3 inches; heat over medium to 275°F. Gently lower potatoes into pan, and cook until potatoes have a light skin on the outside and are soft when pierced using a fork, about 12 minutes. Remove potatoes from oil, and place on prepared rack-lined baking sheet.
5. Increase heat in saucepan to medium-high, and bring oil to 350°F. Gently lower potatoes back into hot oil, and fry until golden brown and completely crisp on the outside, about 6 minutes. Remove potatoes using spider to a paper towel-lined baking sheet, and let drain. Season immediately with additional salt to taste. Leave oil at 350°F.

Fry the fish

1. Whisk together white pepper, 3/4 cup of the flour, and remaining 1 teaspoon kosher salt in a large bowl. Whisk in sparkling water and brown ale, forming a light batter. Place remaining 1/2 cup flour in a shallow dish.
2. Remove fish from brine, and pat dry. Dredge fish lightly in flour; tap off excess flour. Place 1 fish fillet in batter, and submerge completely to coat; lift fish with 1 end, and let excess batter drip back into bowl. Gently lower fish into hot oil, releasing fish when portion of fish in oil starts to float, about 15 seconds. Repeat process with second fish fillet.
3. Fry fish, 2 at a time, until golden brown and crispy, about 6 minutes, turning fish to cook evenly on each side. Once fish are cooked, remove from oil, and place on a wire rack placed over a baking sheet. Season with Maldon sea salt to taste. Repeat process with remaining fish. Serve fish with lemon wedges, tartare sauce, Triple-Cooked Chips, and Modern Mushy Peas.
