I have made some great infused coconut oil man. crockpot with water and oil in it works fine. I also do the re-infusion method in a mason jar double boiled. both come out just fine. I like to make the oil pretty strong. Then I decarb some keif and add it to the hot oil and then stir in corn starch till it is all a jelly like dry substance you can handle with your fingers. It makes it super easy to load a capsule this way. I am not sure how much the oil can saturate to but I have had it come out of the mason jar thick as honey after about six infusions.
