The ones being made were rose creams, a traditional flower based cream made with natural flavouring, dipped in chocolate and topped with a candied rose petal. The cream filling is made from a special powdered sugar not cream. This was rolled into a thin log shape and some melted chocolate spread along it. When the chocolate was set the log was cut into pieces, having this layer of chocolate makes it easier for each piece to be picked up on a fork for dipping into tempered chocolate.
below the finished rose creams, these are also made heart shaped.
