Whether its for an exotic picnic lunch or a midnight snack, Nigella Lawson's Japanese style noodles are irresistible. Cooks notes: I love the Japanese way of eating cold noodles: I just lift a bowl to my face, fork furiously and slurp. If you want to make these part of a meal, then know that they go wonderfully well with salmon: just get some fillets, sear them in a hot pan, leaving the interior fleshily coral. But I love eating these as they are, in huge quantities and - preferably - alone. Because they're served cold, you can profitably keep leftovers for midnight fridge-raiding later. Boxed into foil containers, they are the perfect, if unconventional, food to take along for a picnic.
