Yes, we use the Semper Dark Chocolate Coating Slab from Stover & Co. It works very well for coating truffles. It does not need to be tempered first. It comes in an 11-lb. slab in either dark or white chocolate. It can be microwaved and has a great consistency and flavor. We have not tried the white chocolate yet, but just ordered it today since we have been so pleased with the dark chocolate.
