Cut the pears in half lengthways, remove the cores and sprinkle with lemon juice. Peel and grate (shred) the ½ apple into a bowl and add the cottage cheese, walnuts and raisins. Mix together then add a little Worcestershire sauce and a dash of salt and pepper to taste. Pile the mixture into the hollowed out pear halves and garnish with redcurrants and basil leaves.
