Can I use this to cook with? yes? no?

alright so to begin this, I like to vape with ecig mods. I like also like to dab, so in an effort to combine the two I diluted 3.5 grams of melted bho into around 100mls of propylene glycol. as that was going i did a low heat vegetable glycerin extraction in a few 8hr sessions.
 
that was done with about an ounce of stems and then 8 grams of shake. i didn't record the amount of vg so that kinda fucks trying to figure our the ratios. anyway it turns out i did not make the end mixture
concentrated enough (because i wasn't recording my amounts very well...*ehm*)
 
if I would have done something like a 1/2 gram bho to 15 ml of pg and then 25ml vg with 3g then it probably would have been better dosage. but hey, hindsight is 20/20
instead i have closer to 200mls of this fluid. (i could always just add a fuckton of bho into it to even it out but i only made enough oil to smoke on the last batch so not even going to possibly waste it on this nonsense) 
 
anywho im kinda sick of trying to vape this fluid. it does get you nice and where you need to be, but after a while which was the downfall. I was wondering if it would be possible to cook with it?
 
I know everything in the mixture is edible, but I didn't decarb or activate the thc for consumption in the bho mixture because it was to be vaped but can i do that just by cooking it at this point? 
 
if not then ill probably just end up flavoring it a bunch, because the unflavored taste of it is pretty gnarly
 
anyway, thanks for reading and i'm looking forward to responses.
