Sprinkle the gelatine on to the 1 cup of cold water and leave to soften.
Cook water and sugar to a hard ball consistency (a drop of it dropped in a cupful of cold water should immediately form into a hard lump.)
Take the syrup off the heat and add the gelatine, juices, and coloring at once. Mix and strain through a fine sieve.
Pour into the prepared pan and leave to set. When firm, cut into desired sized shapes, roll in the sugar and serve.
Key Ingredients: sugar, gelatin, orange, lemon juice, castor sugar
