Preheat the oven to 180°C/fan 160°C/gas mark 4. Grease or line 3 baking trays.
Beat the butter, orange zest, mixed spice and sugar together until pale and fluffy. Add the vanilla extract and sift in the flour. Add the dried fruit and orange juice and mix well.
Roll the mixture into small balls using a teaspoon and put them on to the baking trays, spacing well apart. They will spread and flatten into cookies as they bake. Bake for 10-13 minutes until cooked and light golden, but still chewy inside.
