1. Rinse potato chips and soak in cold water for 20 minutes, then drain and pat completely dry. 2. Par-cook chips: heat 2 cups (480 ml) of frying oil in a deep pot to 325°F (160°C). Fry potatoes in batches 4–5 minutes until soft but not browned. Remove and drain on paper towels. 3. Make batter: whisk 1 1/2 cups (190 g) flour, baking powder, salt, and pepper in a bowl. Gradually whisk in cold beer and 3 tbsp (45 ml) oil until a smooth, slightly thick batter forms. Keep batter cold. 4. Heat remaining oil to 375°F (190°C) for final frying. 5. Dust each cod fillet lightly with 1/2 cup (65 g) flour, shake off excess, then dip into the batter to coat fully. 6. Fry battered fillets one or two at a time in the 375°F (190°C) oil until golden and crisp, about 4–6 minutes depending on thickness. Drain on a rack or paper towels. 7. Finish chips: return par-cooked chips to 375°F (190°C) oil and fry until golden and crisp, 3–5 minutes. Drain and season with salt immediately. 8. Mix tartar sauce ingredients in a small bowl and adjust seasoning. 9. Serve blue cod fish and chips hot with lemon wedges, malt vinegar if desired, and tartar sauce.
