Put the sugar and vanilla sugar in a large bowl.

Blitz the cherries in a food processer until finely chopped.

Add the milk to the sugar and stir to dissolve.

Add the chopped cherries and agitate with a whisk to distribute evenly.

Using a jug, pour the cherry milk into an ice cream maker and churn.

After 5 – 10 mins when milk starts to thicken pour in the frozen chopped chocolate.

Carry on churning until ice milk is the consistency of ice cream (about 40 minutes in total depending on your machine).

Pour into a tub and freeze for 6 – 8 hrs. (Makes just over 1 ltr).

To serve, take ice milk out of freezer 10 minutes before serving.
