In a medium pot, heat the sesame oil on medium-low heat, ensuring that it NEVER comes to a boil at any time. After it's thoroughly heated, but not boiling, reduce the heat slightly. Add your trimmings and/or buds and heat for 2 hours on the lower setting, stirring every 5 minutes for the initial 30 minutes. Again, NEVER let it come close to a boil. If it does this, you will have wasted the potency in the trim/bud. After 2 hours, remove from heat and allow to cool for a few minutes, before straining the marijuana matter through a fine screen, ensuring the oil goes into a glass container, such as a mason jar. Store in the refrigerator until ready to use.
