Method
Prepare and fry the chips
- Soak the potato sticks in the cold water for 30 minutes.
- Drain and rinse the potatoes, then dry them thoroughly with a clean towel.
- Pour the oil into a 6-quart Dutch oven and heat it to 325°F, using a deep-fry thermometer to monitor the temperature.
- Fry the potatoes in batches for 5–7 minutes, keeping the oil near 325°F, until tender but not browned.
- Transfer each batch to a wire rack set over a rimmed baking sheet.
- Raise the oil temperature to 375°F and fry the potatoes in batches for 2–4 minutes, until golden and crisp.
- Return the potatoes to the rack and season with 1/2 teaspoon of the salt.
Batter and fry the fish
- Turn off the heat and let the oil cool to 350°F, about 5–10 minutes, monitoring it with the thermometer.
- Pat the cod dry.
- Place 1/4 cup of the flour in a shallow dish.
- Whisk the remaining 1 cup flour with the cornstarch, baking powder, and remaining 1/2 teaspoon salt in a medium bowl.
- Whisk in the cold beer just until smooth.
- Dredge each piece of cod in the flour.
- Dip each piece in the batter, letting excess batter drip back into the bowl.
- Fry the fish in batches at 350°F for 4–6 minutes, turning once, until deep golden and the thickest part reaches 145°F.
- Transfer the fish to the wire rack to drain briefly.
- Serve the fish with the chips.
Notes
Keep the oil near the stated temperatures for crisp chips and evenly fried fish. Refrigerate leftovers for up to 2 days; freezing is not recommended for the best texture. For a gluten-free adaptation, use a gluten-free all-purpose flour blend and gluten-free beer.
