Melt the grated chocolate over hot water to a smooth paste. Remove it from the hot water, beat for a few minutes, adding gradually the rose extract and the melted cocoa-butter. Stir occasionally until quite cold; then rub through a wire sieve on white paper underneath.

Put the sweet chocolate and the unsweetened chocolate into a saucepan, and melt the mixture to a smooth paste; then add the cream, hot syrup, the extracts, and stir over the fire until well mixed. Remove from the fire, and beat until the mixture becomes cold and a lighter color. Mold it into round centers; then roll them in the sieved chocolate.

Serve in paper cases.
