For the venison, place the spices in a blender and blitz until finely ground. Season the venison and coat in the spices. Pour a little olive oil in a pan and sear the venison for 2 minutes on all sides. Remove and leave to rest on a plate.
For the blackberries, add all the ingredients apart from the blackberries into a saucepan and bring to the boil. Add the blackberries and remove from the heat.
To serve, slice the venison and place on a plate. Add the blackberries and a little juice, add the hazelnuts, shavings of Parmesan and finish with the rocket.
