Why not just eat the pot?
High Gravity Brownies
“Take 1 teaspoon black peppercorns, 1 whole nutmeg, 4 average sticks of cinnamon, 1 teaspoon coriander. These should all be pulverized in a mortar. About a handful each of stone dates, dried figs, shelled almonds and peanuts: chop these and mix them together. One quarter ounce of cannabis sativa can be pulverized. This along with the spices should be dusted over the mixed fruit and nuts, kneaded together. About a cup of sugar dissolved in a big pat of butter. Rolled into a cake and cut into pieces or made into balls about the size of a walnut, it should be eaten with care. Two pieces are quite sufficient. Obtaining the cannabis may present certain difficulties.... It should be picked and dried as soon as it has gone to seed and while the plant is still green.”
