Advancements in healthcare devices and clinical-grade medical monitoring systems necessitate realistic phantom models for rapid, cost-efficient, and precise testing. This paper introduces novel recipes for bone tissue phantoms and examines the impact of temperature during the development phase on the dielectric properties of the final phantoms. Only non-toxic, environmentally friendly ingredients are used in the development process. The new bone recipes are designed for both cortical and cancellous bone tissues. Additionally, a bone average phantom is created using the same recipes with temperature adjustments during development. The effect of cooking temperature is also studied for a brain phantom recipe. The measurement results indicate that the cancellous bone recipe can be used to create both cancellous and average bone tissues by applying cooking temperatures of 65  \(^{\circ }\) C and 85  \(^{\circ }\) C, respectively. The cortical bone recipe requires cooking at 85  \(^{\circ }\) C to achieve the dielectric properties of cortical bone tissue while cooking at 65  \(^{\circ }\) C yields the bone average. Temperature studies on the brain phantom recipe show that an average brain is obtained at a cooking temperature of 85  \(^{\circ }\) C, whereas white matter is obtained at 65  \(^{\circ }\) C. This study demonstrates that the same phantom recipe, when cooked at different temperatures, can be used to fine-tune phantom properties for specific application scenarios. It serves as a starting point for the development of a uniform phantom system that can mimic the dielectric properties of multiple biological tissues.
