WHAT YOU NEED
3 cups of filtered water
3 cups fine granulated sugar
2 tablespoons vegetable glycerine (found at most health food stores)
2g finely chopped/ground cannabis
1 jar or bottle
1 saucepan
Strainer or cheesecloth
HOW TO MAKE
Add the sugar and water in the saucepan. Bring to a boil.
Stir until sugar is completely dissolved then add the cannabis. Cover the pot and allow it to boil gently for another 20 minutes. This is the most important step as the heat will decarboxylate the cannabis. This is also when the THC will be transferred into the syrup.
To prevent the liquid from getting too hot, keep the liquid at a low roiling boil.
At the 20 minute mark, reduce the temperature. Add the glycerine.
Let the mixture simmer for another 5-6 minutes, keepign a close eye on the pot. Remove the lid and stir quickly every minute.
Remove the pot from the heat. Carefully pour the hot syrup through the strainer or cheesecloth into your container. Go slowly. The idea is to remove all plant matter from the syrup - plus, you don’t want to risk burning yourself.
Let the mixture cool. It will have reduced slightly in this process. However, you should have about 3 cups of syrup.
The gylcerin is apparently not required, polysorbate 80 or 20 could certainly be substituted. or folks are just running without.
Note: this will get you syrup. it will not get you water soluble cannabinoids.
