Roast the pine nuts in a pan without fat until light brown, take them out. Chop white couverture and melt with coconut oil on a hot water bath. Pour 2 tablespoons of this into a small piping bag with a perforated spout. In the meantime, dice the plums a little smaller. Mix pine nuts, plums and smacks into the chocolate coating. Place crossies with a teaspoon on trays covered with parchment paper. Decorate with couverture from the piping bag and let dry
