@dobroeutro may be able to help with that.
I'm not a fruit lover, but do use them as accents/companions in a variety of mixes. I have not as yet ventured into any of the VTA fruits, so really have no idea about percentages. I do have several flavored puddings aging. So far, I like the Pudding Base @ 4% with 1% Custard (INW) as the base. I generally start @ 50 - 60% complimenting flavor(s) to base. What I've mixed so far:
Chocolate Pudding
Pudding Base (VTA) 4%
Chocolate Chunks (WF) 2.25%
Custard (INW) 1%
Australian Chocolate (Hangsen) .75%
Hazelnut (FW) .5%
Vanilla Pudding
Pudding Base (VTA) 4%
Vanilla Overload (Gremlin) 2%
Custard (INW) 1%
Vanilla Shisha (INW) 1%
Coconut (FA) .5%
Pistachio Pudding
Pudding Base (VTA) 4%
Pistachio (TFA) 2%
Custard (INW) 1%
Almond (FA) 1%
Vanilla Shisha (INW) .5%
They're still young, so the results are still out & I'll likely make adjustments...
