So by evapping before freezing one raises the concentration of spice per/ml of naptha thus forcing more spice to crystallize out. But if you're reusing the naptha couldn't you just avoid that evap, take what you get, and then reuse the naptha next time and retrieve the spice when the naptha is more saturated from future pulls? It seems like doing it this way would save a step and save naptha. What do you guys think?
