my first tek was Nomans, it is about as easy as it gets, but you will yield more with an AB extraction. But most of these are "easy" and have been spelled out step by step. If you do go the Nomans route, I would add the salt as per Cyb's tek. Otherwise, go with Cyb's as per Cyb's recommendation

also very easy.
All amounts pretty much scale proportionately.
