Starting a new thread because I can't be arsed finding one of the old ones.
So I got lazy wanting for my steeping custard to try
@zouzounaki's recommendation of one drop per 10ml in custard vapes. I made myself up two 10ml batches of shake and vape custard (4% LB vanilla ice cream, 0.5% FLV vanilla pudding) and added one drop (came out at 0.2%) to one of them.
Both bottles taste completely different. One is custardy and the other one all I can really taste is the condensed milk, not unpleasantly so as I know this can be, it's actually really nice but maybe still too much for me.
I'm looking forward to playing with this some more, may even make myself a dilution to try it in even smaller quantities (akin to TFA cinnamon spice).
Other people may differ to me though as we all know taste is subjective. I already know I have a strange pallet when it comes to vaping. I don't taste strawberry, I'm very sensitive to TFA honeydew (0.5% and still only taste honeydew), TFA cheesecake graham crust has nothing but crust. Luckily I'm not a pepper taster for vbic though.
