Drain on a rack. Wet potatoes make oil spit, so dry them well, and if the oil ever catches fire, cover it with a lid; never use water.

Cook's tip
Frying twice gives chips that are crisp outside and fluffy inside; do the first fry ahead and finish just before serving. Once the butter is in, the sauce will split if it boils, so reheat it gently only.
Cooking it at camp
Deep-frying at a campsite is a real fire risk, so skip the chips or grill potato wedges instead. Finish the sauce at home; on site, cook the meats, stack the sandwiches and melt the cheese under a lid over low heat.
