K, here's what you do.
Get a quick read thermometer, or one you leave in.
Get whipping cream, 33% or half and half, higher fat the better.
Get a nice pot.
Chop/Grind/Cut/Powder your bud (I personally use stem, cause I just save till i have a bunch n,n)
Submerge material in cream, heat on low (bout 1-2 on my stove) with a lid, uncover and stir or cover and shake the pot to coat the material and dislodge the THC.
Heat till 76c(168.8F), kill heat, cover tightly. 76 is the point where all the thc acid has turned to active, but some is starting to vaporize at this time, so we must cool it down/trap the airborne THC ASAP.
Keeping the lid on TIGHTLY(if your lid sucks, take it off the heat, into the ice bath at 77c(170.6F) and pray for the best), let the heat of the pan bring it up to about 78-80c (172.4-176F), meanwhile prep an icewater bath to cool the pot, i personally salt the ice (just make sure not to get any in the milk =P) to make it go faster.
Cool to 60c(140F) or below
Enjoy.
