I will be making a batch of qwiso in the near future and i wont to get it right.I know not to use any heat just use fan and that is all.Do i need to use heat after it has all purged to make sure i get any remaining iso out of it.If so can someone tell me the way i should go about this?This is the idea i have tell me if i am wrong or not.I plan on heating it just enough to scrape it all up onto parchment paper.Than tranferr the parchment paper with oil on it to a skillet on a electric burner and than heating it.The only thing is i dont wont to burn all the good stuff out of it.Can someone give me some tips on this matter please?
