dry ice extraction w/5oz of trim to make butter for patient. some Q's for you experts

ok, I have a patient of mine that would like some edibles. I have about 5oz of trim and popcorn nugs from my last harvest (dried and in the freezer). I would like to get the most of my trim. my thoughts are to do a dry ice extraction, to pull the most trichs from the trim, then make butter from the keif extracted. my question is how much of the keif should I use per pound of butter? I don't want to make my brownies/cookies too strong for my patient, but I don't want them to be too weak either. whats a good ratio of keif to butter? my trim and popcorn came from some bomb/fire medicine, not schwag.

thanks everyone. ive made cookies in the past, but never really knew the weight of the keif cooked in the butter and just went with it. end result put me and my buddies in the couch for hours. lol which is not a bad thing if you wanna look at it that way.

I thought about not responding, I know you were looking to sieve it, but I must say that a quality sieve leaves a lot on the plant. I would do a solvent extraction and put that in butter...

I'll also be doing the dry ice hash down the road because it's so much easier and safer and would like to know the answer to the OP's question. I have a knack for breaking things and really don't trust myself not to blow up the place.

ive done qwiso extractions in the past, and still have about .75g of finished oil in my goodie box. I thought a dry ice extraction would be simpler/quicker and result in a better yield than an iso pull. I already have the bags ( needed. I have a pregnant wife, and its cold today, so if I do an iso pull, id have to evap it in my garage (dirty/dusty). id rather not go that route. so the dry ice is more feasible.

if from my trim/popcorn dry ice extractions, I was planning on using 7g for making some cookies, and the rest in an iso extraction (when I have the time). ive used extracted kief in iso extractions before. lessens the chance of any chlorophyll and a better end result.
