Howdy all! This is a question I've thought up while at work. I know that in the old school enfleurage process of extracting essential oils, they would take beef fat or pig fat and allow the plants to soak inside it, then distill it to obtain essential oils. (A recent movie about this subject was released with Dustin Hoffman in it, got the wheels turning inside my head...) Is it possible to measure your set amount of lard/tallow, melt it, and then allow the cut up leaves and stems of fragrant plants (Lavender, Rosemary, Mint, Gardenia, Pine Needles, Etc.) to stew inside of it, filter them after the oil changes color and absorbs scent, and use it in your soap making recipe? I'll have to try it when I get home I think!
