Pre-heat the oven to it's lowest fan-forced setting and line a baking tray with a silicone baking mat.
In a blender, puree the fruit together then transfer it to a small saucepan.
Add the sugar and lemon juice and simmer for 8-10 minutes, stirring every now and then.
Spread the mixture onto the baking mat using an icing spatula and make sure that is is evenly spread and the same thickness all over.
Bake for 4 hours, or until the fruit spread is a little bit sticky, but still firm to the touch.
Take the tray out of the oven and allow it to cool slightly then transfer it to a sheel of baking paper.
Use scissors to trim the edges then cut thick strips, roll them up and tie them with kitchen string.
