Provenance has been identified as an emerging and important concept within the Grid community for a variety of purposes, such as verifying or tracing results. We seek to provide a concrete conception of provenance and its possible utilisation through the process of designing and implementing a system prototype with some specific provenance requirements. This prototype, which is based on an idealised recipe for baking a cake, is developed within the context of a service oriented Grid computing environment and implemented using standard Web Services technologies. The issues surrounding the design of possible provenance system are also explored
