It doesn’t really need any IME. Some people do cure it, though… quick info that I found.
HOT CURE ROSIN
Hot curing involves applying some kind of heat cycle to your rosin, and there are a multitude of ways to achieve this. However, the most common hot cure method involves popping the jars in an oven at around 200°F for an hour or two, and then allowing them to cool.
Ultimately though, there are no hard or fast rules regarding the temperature or duration of this heat cycle, and we highly recommend that you experiment with both variables.
COLD CURE ROSIN
Conventional wisdom has it that hot temperatures tend to degrade the volatile terpene profile of your rosin, and while it’s highly debatable how much is lost with a hot cure method, many terpene conscious rosin makers prefer cold curing instead. The belief being that cold temps help preserve the delicate terpene profile of solventless rosin.
As with hot curing there’s a huge amount of variation in technique with cold curing. Some may simply use room temperatures, others may pop the jars in a refrigerator, and some even use a freezer. Again, we recommend that you experiment with both temperature and duration of your cold cure.
