Fish and Chips
Fish and chips come down to timing: the potatoes are fried twice, the cod once, and the order lets both reach the table hot and crisp. Soaking the cut potatoes in cold water rinses off surface starch, and the first fry only cooks them through, ending before they take on deep color. Cold sparkling water in the batter, mixed only until a few small lumps remain, keeps the coating light rather than bready. Any surface moisture on the potatoes or fish makes the oil spit and leaves patchy crispness, so both are dried well first. The cod is done when the crust is golden and the flesh separates cleanly into flakes. Serve right away, before steam softens the crust.
