Add the grass fed beef tallow and beeswax to a heat safe bowl set over a double boiler. Heat gently over low heat until fully melted. Avoid high heat to protect the quality of the oils.
Remove from heat and allow the mixture to cool slightly. Stir in the rosehip oil, calendula oil, and honey while still liquid but not hot.
Add essential oils if using and mix well. I prefer to mix vigorously to insure that the honey gets incorporated.
Pour into a clean jar and allow to cool at room temperature until fully set. The balm will firm as it cools but remain soft enough to scoop easily.
