I am fairly new to DIY, just started this year. In cooking recipes you do things in a certain order. Don't follow the order and the final result can change. I am curious if we should be doing this with e-liquids. Perhaps a professional or even a really good cook can share their opinions. I currently, like most people I imagine, put all the ingredients in a bottle and shake. Should we mix the flavors first then add pg then vg? Any help with this is appreciated.
