Heat the oil in a large non-stick frying pan over a low heat and fry the garlic for 2-3 mins, or until just turning golden at the edges. Remove from the heat and leave for 15 mins for the garlic to infuse in the oil.

Meanwhile, cook the pasta following pack instructions until al dente. Drain, reserving 150ml of the cooking water. Remove the garlic from the infused oil, then tip in the cooked spaghetti, the chillies, anchovies, parsley, lemon zest and juice, and the parmesan. Add 50ml of the reserved water and toss with tongs until combined. Add a little more water to loosen, if you like. Season. Divide between four shallow bowls.
