I made some using MCT oil this weekend and it worked out well.
I took about a half oz of mostly bud, chopped it up with scissors, toasted at 320f in the oven for 10 mins, let it cool. Put it in a crock pot and crushed it down some more with a fork before adding not quite 2 cups MCT oil. Simmered on low 4 hours, might do it longer next time. Stirred frequently. Once it was cool enough to handle I strained it through cheesecloth & squeezed it out hard, then poured back into a dark bottle for the fridge. Lot less tricky than dealing with boiling water and butter.
Wasn't going for a super-strong oil this time but it's got a kick. I was aiming for something to use in place of regular cooking oil. Might try to make it stronger if I was going to put it in a dropper bottle and be able to take only a little to get high. As it is one brownie did just fine. Looking forward to trying two.
Use lowest temp even in the crock pot. MCT is no good for frying but good for baking, adding to dressings, probably even a smoothie. It has no real flavor of its own, bland so it can go with lots of things.
