I simmer my buds/shake/trim in a pot of water for about an hour+ first..
Then i filter out all the leaf material..
Then i add the oil to the water, and simmer again for another hour+...
The ratio of water to oil always being at least 5:1(you cant have to much water...), because if there isnt more water than oil the oil would be poppin all over the place...
Doing it like this you can make small single use (4-8oz) batches of oil or big long term batches if you wanted too...
After i let it simmer for a second time, i take it off the heat and let it cool to around 100 degrees...
Then i pour the oil/water mixture into a Separating Funnel, to separate the Oil from the Water..
Presto Pure Ganja Oil, but since i used an Oil/Water mixture only the good stuff is in the oil, and the unneeded chemicals can be discarded with the water...
Making for an Odorless and Tasteless not to mention Clear byproduct...
A Separating Funnel can be made by using a simple Ziploc Bag tilted on an angle... (if youve made ether, im sure your quite familiar with this..)
Even if the mixture was 150 degrees the oil and water still would separate instantly,
But its easier to manipulate when cooled down....
Pour the mixture into the Ziploc bag, tilt to one side so one of the bottom corners is pointing down...
Have a cup or bowl handy for this next step...
Cut a small part of the tip off and let the water drain into the sink or a second bowl first, as soon as the oil starts to drain catch it with the prepared cup/bowl..
And thats it..
Its not as simple as chuck some oil and Buds in a pot and filter, but this way the oil will have no residual Pot taste, and when you cook with it anything you make will be indistinguishable from food made with regular oil...
