I have tried it, but not with an orange flavor, the flavor itself was so bad, (I was going for orange creamsicle and it was GROSS.) I just thought back lovingly to "Pimms, a l' orange" which is impossible to get around here, but it's one of my favorite biscuits.
So, I added some dark chocolate to the failed mix I already had, it did not improve it much, but it did hint to me that if I got a good orange flavor, some dark chocolate (no cream whatsoever, that kinda works against dark chocolate in my opinion) I could create something similar, using a biscuit flavor, some dark chocolate, and a decent orange. I'm not sure if a sweetener would be required, but if I ever tried to make that mix successfully, I would definitely try to do without it first. The concoction (Pimm's) really isn't sweet at all, it definitely leans to bitter. But, I might give it a shot someday, if I ever get invested enough into trying it. Not sure how it would
vape, but ideally I'd want the bitter up front, and then kind of the biscuit flavor on the exhale. I'm thinking I'd need to experiment....
