2.5kg bag of potatoes, cut into chunky chips
3 tbsp plain flour
10 tsp olive or sunflower oil
Salt and pepper
Bring two large saucepans of water to the boil (or prepare the chips in batches if you don’t have enough big pans). Add the chips, bring the water back to the boil and boil for 3 minutes, then drain the potatoes well and tip into one or two large kitchen-paper covered trays. Scatter with the flour and some seasoning and gently toss to coat (Can be frozen in freezer bags and cooked from frozen)
Heat oven to 200C/Gas Mark 6. In a baking tray toss the chips in the oil and roast for 35-40 minutes until crisp and golden.
