Fish & chips
Scrub the potatoes, cut into 1.5cm thick lengthways slices, then cut each slice into 1.5cm thick chips. Tip the chips into a large saucepan, pour in enough water to just cover, bring to the boil, then lower the heat and gently simmer for 4 mins only. Drain, tip onto a clean tea towel, pat dry, then leave to cool. Can be done 1-2 hrs ahead. Heat oven to 220C/fan 200C/gas 7. Put a large shallow non-stick roasting tray in the oven with 1 tbsp olive oil and heat for 10 mins. Transfer the chips to a bowl and toss in the remaining oil using your hands. Tip out in a single layer onto the hot roasting tin. Bake for 10 mins, then turn them over. Bake 5 more mins, then turn again. Bake for a final 5-8 mins until crisp. Drain on paper towels. While the chips are in the oven, cook the peas in boiling water for 4 mins. Drain, then tip into the pan and lightly crush with the back of a fork. Mix in the oil, lemon juice and freshly grated pepper. Cover and set aside.
