well dosage will take some math, and your own taste
but first coconut is the best to use, hisghest bioavailability without doing anything crazy. . .and the flavor can compliment many dishes.. but you can still use actual butter
personally i like 300mg of hash/oil per serving. some with less tolerance may want 200. new med users that have no tolerance and not necessarily trying to get blasted may like 100...its personal preference
but whatever recipe you use, you know, figure how much coconut oil would be in each brownie or carrot cake slice whatever lol. this is all up to you.
how old is that trim?
it will decarboxylate at room temp in a few months.
hopefully youve limited light exposure.
i generally tell people to decarb in a double boiler, it keeps a pretty stable temp and just watch the bubbles slow like popcorn to know when its done.
if the grade your using for baking doesnt melt nicely, you can certainly add some oil during the decarb. you can decarb while in solution and will actually help prevent some oxidation with the heat.
once you have the "activated" hash. simply heat some of whatever carrier you choose to melting point and dissolve in the hash.
the steps to make traditional butter with trim use say a crockpot and much longer times, and causes the flavor to be leached and more sedative, not just from relatively more cbd but cbn being produced as well.
the baking process also does this to some extent.
if you want a high as close to the bud as possible... try capsules, no baking
but there is something nostalgic about a good weed brownie.
anyway good luck, if i didnt help or clear up enough ask away
