Place the sugar and water in a saucepan and heat until the sugar has dissolved. Remove from the heat and set aside to cool.

Using an electric mixer, whisk the sugar syrup with half of the ready-made apple sauce. Once combined, add the rest of the apple sauce and mix together well.

Transfer into a metal bowl or dish and place in the freezer. Every hour, beat the apple sorbet for 5 minutes to break up the ice crystals until firm. Place back into the freezer until ready to serve.
