Drain the cherries. Knead marzipan with 50 g icing sugar and lemon juice. Form into a roll and cut into 20 pieces. Flatten each piece of marzipan, place one cherry in the middle of each piece, cover with marzipan and form into balls.
Melt the chocolate coating in a hot water bath. Let it cool down a bit and cover the marzipan balls with it. Let it dry on aluminium foil. Mix the rest of the icing sugar, a few drops of cherry syrup and food colouring to a creamy glaze.
Pour into a small freezer bag, cut off a very small corner and decorate the marzipan cherries spirally with it.
