An expert adaptation combining food science with time-honored pub traditions. Features an ultra-crisp beer-and-vodka leavened batter and pillowy, triple-cooked chips.

Instructions

01

Fish Prep and Osmosis

Pat the fish fillets dry with kitchen paper. Sprinkle 1.5 teaspoons of fine sea salt evenly over all sides. Place the fish on a wire rack inside a tray and refrigerate for 15 minutes. Afterward, rinse thoroughly under cold water and pat completely dry with fresh paper towels.

Why it matters

Salting draws out excess internal water and tightens the muscle structure, preventing steam from making the inner batter layer soggy.

Look for

The fish flesh should look firmer, slightly translucent, and feel tight rather than flabby.

02

Shape and Simmer Chips

Peel and cut potatoes into chunky sticks ($1.5\text{ cm} \times 1.5\text{ cm}$). Wash under cold water for 2 minutes. Place in a pot with cold water, 1 tbsp malt vinegar, and a pinch of salt. Bring to a gentle simmer over medium heat and cook for 10–12 minutes.

Why it matters

Vinegar slows pectin breakdown, allowing the interior to cook completely without the outer edges collapsing into mush.

Look for

The chips should be knife-tender but hold their shape, showing tiny micro-fissures along the edges.

03

Evaporation and Freezing

Carefully lift chips into a clean colander. Shake firmly to rough up the edges. Let them sit until they stop steaming, then transfer the rack directly into the freezer for 30 minutes.

Why it matters

Roughing up the surface creates tiny pockets of starch that crisp up intensely. Freezing eliminates residual surface moisture.

Look for

The chips should look dry, matte, and have fuzzy, ruffled surfaces.

04

The Chip Blanch (First Fry)

Heat frying oil or melt beef tallow in your pot to exactly 130°C. Lower the chilled chips into the oil in batches. Fry for 6–8 minutes without allowing them to color. Remove and arrange in a single layer on a clean wire cooling rack. Return to the fridge or freezer until completely cold.

Why it matters

This initial low-temperature blanch gelatins the internal starch into a soft paste while establishing a protective outer skin.

Look for

Pale blonde, slightly wrinkled chips that are dry to the touch.

05

Whisk the Batter Matrix

In a large bowl, whisk together 100g plain flour, cornstarch, baking powder, turmeric, and a pinch of salt. Pour in the ice-cold beer and vodka. Whisk briefly for 10–15 seconds until it reaches a double cream consistency. Leave small lumps.

Why it matters

Cold alcohol prevents gluten from bonding tightly, creating a fragile, glass-like expanded expansion shell instead of a bready coating.

Look for

A shiny, aerated wet batter that leaves a thick trail when drizzled.

06

The Crispy Fish Finish

Raise oil temperature to 170°C. Coat a fish fillet in the 50g dry plain flour, shaking off excess. Dip into the wet batter. Hold over the bowl for 3 seconds, then lower carefully into the hot oil, holding the tail end for 5 seconds before releasing. Once floating (around 1 minute), drizzle threads of remaining wet batter over the fish. Fry for 5–6 minutes total, turning once.

Why it matters

Holding the tail prevents bottom-sticking, and the extra drizzle creates light, crispy shards on the exterior crust.

Look for

An expanded, deeply golden crust that sounds hollow and rigid when tapped with tongs.

07

The Final Chip Blast (Second Fry)

Transfer the fried fish to a 120°C oven on a wire rack to keep warm. Crank the frying oil to 190°C. Drop the cold, blanched chips into the oil. Fry for 3–4 minutes until rich golden brown. Lift out, shake off oil, toss in a bowl with flaky sea salt, and serve immediately.

Why it matters

High heat vaporizes remaining moisture in the outer crust instantly, perfecting the contrast between crunchy exterior and fluffy interior.

Look for

Deeply golden, rigid chips that rattle like dry wood when tossed.

08

Prepare Minted Mushy Peas

Melt butter in a small saucepan over medium heat. Add frozen garden peas and chopped mint. Cover and steam in their own juices for 5 minutes. Remove from heat, add lemon juice, season with salt and pepper, and mash roughly.

Why it matters

Cooking peas in butter without adding extra water concentrates natural sugars, while fresh mint cuts through the richness of fried food.

Look for

A thick, chunky green paste with visible bits of crushed pea and mint.

Common mistakes & fixes

  • Using warm or room-temperature carbonated liquids, which causes the bubbles to dissipate prematurely before hitting the oil.
  • Overcrowding the pan, causing oil temperature to plunge, making the food greasy and soft rather than crispy.
  • Why is my batter separating from the fish surfaces— The fish was likely damp before dredging. Ensure you dry the flesh completely with paper towels and coat it evenly in dry flour before dipping it into the wet batter.
  • Why are my chips browning too fast on the outside while staying hard inside— Your potatoes are likely too low in starch or your oil was too hot during the first blanching phase. Stick to floury types like Maris Piper and keep the first fry strictly at 130°C.

Substitutions

  • Vodka → Sparkling Water. Increases gluten development slightly; the crust remains crisp but will soften faster over time.
  • Light Lager → Non-Alcoholic Ginger Beer. Adds a hint of sweetness and accelerates outer browning due to natural sugars.
  • Beef Tallow → Peanut Oil or Sunflower Oil. Provides a clean, neutral flavor profile with excellent high-smoke stability.

Storage & reheating

  • Fridge: Store leftovers in an airtight container for up to 2 days.
  • Freezer: Not recommended for fully assembled components once fried.
  • Reheat: Reheat in a single layer in an oven or air fryer at 200°C until the crust crisps up again. Avoid microwave heating.
