Palm oil should be melted and thoroughly mixed before you measure it out for a recipe. Palm especially has a habit of the different fatty acids separating out when solid, so it needs to be melted and re-mixed to make sure you get the right amount of all of them! IIRC from her Soap Queen videos on YT, the Brambleberry bags are designed so that you can melt them either in a pot on the stove, or in the microwave.
