If 100% alcohol wasn't used there will be a considerable water content to be removed. To remove it place the extracts into a Pyrex baking dish and leave in the oven with the heat set to the lowest possible setting. After all the moisture is gone the tar can be scaped up while still warm and stored. To remove any harsh tasting substances from cannabis tar boil in 5 volumes of water for 10 minutes, cool down to room temperature and refrigerate the cannabis seeds. Recover the tar and discard the water. Cannabis cooking brandy is not meant for pleasurable drinking. It may be used in any recipe that calls for rum or brandy, such as mince pie, rum babas, rum- or brandy-soaked pound cakes and egg nogs.
