In a large pot, combine the sugar, cinnamon, allspice, cloves and salt. Mix well. Into the same pot, add the pears, orange, lemon, apple and apricot. Mash together.
Stir in the grape juice, vinegar, sultanas and currants. Bring to the boil over medium heat, stirring often. Simmer uncovered until thick.
Spoon into hot sterilised jars to within 1/2 cm of jar top. Seal. Check seal - the top of the lid should not move when pressed. If seal isn't good refrigerate and use within 1 week. If stored in well-sealed containers in refrigerator, it keeps at least one year!
