Remove the rested pasta dough from the fridge and roll through a pasta machine into a long thin sheet.
Cut the pasta sheet in half lengthways and keep one half covered with a tea towel to prevent it drying out.
Lightly brush the reserved sheet with water.
Cut the pasta into small squares and place onto a tray dusted lightly with flour.
Bring a large pan of salted water to the boil and cook the pasta until al dente.
Drain well, drizzle with a little extra virgin olive oil and leave to cool slightly.
Rinse the capers under cold water, dry well and roughly chop.
Heat the vegetable oil in a pan over a medium heat.
Add the garlic, fresh chilli and half of the anchovies. Cook gently, stirring until the anchovies dissolve into the oil.
Leave to cool slightly, then stir through the peeled plum tomatoes, black olives and capers.
Toss the pasta with the radicchio, watercress and puttanesca dressing.
Finish with the remaining anchovies, pecorino shavings, fresh parsley and balsamic reduction.
