Wow

Thanks to all who answered me! Plus % suggestions and recipe ideas--which I even have most of the ingredients to attempt--yippee!
I haven't actually worked with these concentrates, but I have been messing around with vendor-mixed single flavors, including what I believe to be TFA graham cracker and TFA cheesecake. I know, totally imprecise and unscientific..*slaps own hand* I have only a vague idea what the percentages of my mixtures are. But I gotta work with what I have.
So, I too have found this muting effect--where the cheesecake flavor (such as it is :/) takes over the fruits. Actually, I find this is true of the graham cracker as well, maybe even moreso: I have to add much less than I think I need to the mixture because somewhere between a few hours to a day or so in, it seems to absorb the other flavors somehow, leaving me with something that is too sweet, yet somehow also sour and bland...if that's even possible. It makes the muscles in the back of my mouth/jaw contract to remember it... if you know that feeling?

I'm guessing this has something to do with acetyl pyrazine (in both CC & GC, right?) overload, but I am not at all sure.
I did have a couple of very happy accidents adding both lemon and strawberry to a cheesecake base, along with a little whipped cream. Sadly, as the (2mL) tank got vaped down, the flavor mutated on me into that unspeakable stew I was mentioning. Real fast, in other words. I guess I'll be as sparing as possible with both and first try out the lemon bar you offered, MasteroftheVape. (or at least an approximation of it). I do so luurve lemon bars. I wonder if pie crust would fit in there or act funny with graham cracker.
Thanks so much for your input! If I have something intelligible to report back, I will.
Edit: Thanks also for clarifying that the cheesecake graham cracker flavor IS a mixture of cheesecake with graham cracker.
Editagain: Does anyone have a cheesecake flavor (non TFA) they prefer?
