Tips
Soak cut potatoes in cold water for 15-30 minutes before baking to remove excess starch, ensuring crispier chips with less moisture.
Press cornflake crumbs firmly onto egg-washed cod so they adhere during baking rather than falling off.
Make tartar sauce ahead and chill for flavors to meld, improving tanginess and depth.
Good to Know
Tartar sauce keeps refrigerated up to 5 days. Leftover baked chips and cod are best consumed within 1 day; reheat chips in a 180C oven for 5-8 minutes to re-crisp.
Prepare tartar sauce up to 1 day ahead. Cut potatoes and soak up to 4 hours, keeping submerged. Prepare breading station (flour, egg, cornflakes) 2 hours ahead, covered.
Serve immediately while chips are crispy and cod is warm. Provide lemon wedges, tartar sauce, and malt vinegar at the table for individual seasoning.
Common Mistakes
Skip soaking potatoes to avoid soggy chips with dense texture.
Don't crush cornflakes finely to avoid large uneven pieces and uncooked spots on fish.
Pat cod and potatoes dry before cooking to avoid steaming instead of crisping.
Use medium-low broiler heat to avoid burning cornflake coating in final step.

Full guide →FAQ
Can I make this with frozen cod fillets?
Yes, but thaw completely and pat very dry before breading. Frozen fillets release more moisture, which prevents proper crisping. Add 2-3 minutes to baking time if still partially frozen.
What if my chips aren't crispy after 30 minutes?
Oven temperatures vary. Broil for 2-3 minutes, watching closely, or extend baking by 5-10 minutes at 200C. Ensure potatoes are cut evenly and dried thoroughly before baking.
How long can I keep leftover tartar sauce?
Refrigerate in an airtight container up to 5 days. The mayonnaise-based sauce may separate slightly; stir before serving. Freezing not recommended due to mayo breakdown.
