BEST LAYS CHIPS RECIPES

Steps:

• Peel the potatoes and cut lengthways into roughly 1cm/½in slices. Cut each slice into fairly thick chips and rinse in a colander under plenty of cold water to remove excess starch. (If you have time, it's worth letting the chips soak in a bowl of cold water for several hours, or overnight.) Pat dry with kitchen paper.
• Heat a deep, heavy-bottomed saucepan half-full of the sunflower oil to 130C. It's important to use a cooking thermometer and check the temperature regularly. Alternatively, use an electric deep-fat fryer heated to 130C. (CAUTION: hot oil can be dangerous. Do not leave unattended.)
• Using a large, metal, slotted spoon, gently lower half the chips into the hot oil and stir carefully. Fry for ten minutes, or until cooked through but not browned.
• Remove the chips from the pan with a slotted spoon and set aside to drain on plenty of kitchen paper. Repeat the process with the remaining chips. (The chips can be left for several hours at this stage.)
• When ready to serve, reheat the oil to 190C. With a slotted spoon, lower all the par-cooked chips gently into the pan and cook for 4-5 minutes, or until crisp and golden-brown. Remove from the pan with a slotted spoon and drain on kitchen paper.
• Tip into a serving dish and sprinkle with salt and vinegar to serve.

Steps:

• Thinly slice the potatoes on a mandoline, about 1/16 inch thick. Transfer to a medium bowl and run under cold water until almost all the white starch comes off and the water runs clear. Dry well between a couple paper towels. Dry the bowl as well.
• Add the dry potatoes back to the dry bowl and toss with the oil, 1/2 teaspoon salt and a few grinds of pepper until evenly coated. 
• Preheat a 3.5-quart air fryer to 320 degrees F. Shingle the potatoes in the bottom of the basket; it’s okay if there are two layers. Cook until the potatoes are deep golden brown around the edges and crisp, tossing every 5 minutes with tongs so they’re evenly cooked, about 30 minutes. If you notice a few slices are finished cooking and completely crisp before others, remove to a large bowl and continue cooking the remaining pieces. 
• Season the chips with a pinch of salt. Serve immediately or let cool and store in an airtight container for up to 2 days.
