Lake Whitefish from Lake Huron is a familiar catch around Manitoulin Island. Local fish-and-chips kitchens serve portioned whitefish in a lightly seasoned batter, but each cook's formula differs. This home version coats fillets in a delicate wheat-flour and cornstarch batter, fries them until crisp and serves them with lemon. It is one practical island-style fish fry, not a restaurant's confidential recipe or a single island-wide standard.

Step 1If frozen, thaw the fish in the refrigerator. Check each fillet for pin bones, pat very dry and keep chilled while making the batter.
Step 2Whisk the flour, cornstarch, baking powder, salt and pepper in a bowl. Pour in the ice-cold sparkling water and stir just until no dry pockets remain; a few small lumps are fine. Rest for 5 minutes.
Step 3Pour the oil into a heavy, high-sided 20 cm pot to a depth of about 5 cm; the pot must be no more than half full. Heat to 175°C and check with a thermometer. Do not let it smoke.
Step 4Pat the fish dry again. Dip one fillet at a time in the batter, let excess drip back into the bowl, then lower it carefully into the oil. Fry only one or two pieces at a time so they do not touch.
Step 5Fry for about 3–5 minutes total, turning once if needed, until the coating is crisp and pale gold. Insert a clean digital thermometer sideways into the thickest fillet; its centre must reach 70°C. Continue cooking if needed.
Step 6Transfer the fish to a wire rack over a tray so steam does not soften the underside. Let the oil return to 175°C before the next batch; keep cooked fish separate from raw fish and its plate.
Step 7Serve at once with lemon. Refrigerate leftovers in a shallow container within 2 hours at 4°C or colder; eat within 2–3 days or freeze. Reheat once to 74°C.
Serve with lemon and tartar sauce; fries, a dinner roll and coleslaw make a familiar fish-fry plate. Keep children away from hot oil, never leave the pot unattended and keep water out of the oil. Let used oil cool completely before safe disposal; do not pour it down the drain.
Rounded estimate per serving, assuming about 140 g cooked Lake Whitefish, 15 g dry batter solids retained and 12 g oil absorbed. Canadian Nutrient File food 3169, baked Lake Whitefish, is used as a cooked-fish proxy; generic flour, cornstarch, salt and canola-oil values complete the estimate. Fish composition, batter pickup and oil absorption vary; this is not laboratory analysis or package-label nutrition.
Check the cornstarch package for precautionary allergen statements. Contains fish and wheat. Check packaged flour for precautionary allergen statements. Keep raw fish cold and separate from ready-to-eat foods; wash hands and clean utensils, thermometer and surfaces after handling it. Cook the centre of the thickest fillet to 70°C. Chill leftovers within 2 hours at 4°C or colder, use within 2–3 days or freeze, and reheat to 74°C.
Yes. Thaw it in the refrigerator, drain it well and pat it dry before dipping in batter. Do not thaw fish on the counter.
