Take the mascarpone balks out of the blister and cut each in 4 pieces.
Melt the chocolate and mix with the sunflower oil and the powder coloring by using a hand mixer. Stick a toothpick into the frozen mini balks and coat them with the chocolate. For the black mini balks spray the white-coloured balks with black spray coating or air brush. Cover them with plastic and defrost in the fridge or store in the freezer.
