Good point @VapeLuvr. You are correct; this does start to "come to life" after about a week. Vanilla Swirl is another early alternative to remove the A/AP from their Vanilla Custard which they renamed Vanilla Swirl instead of calling it Vanilla Custard DX. As a "custard" it takes time to get really good. VBIC, though not a true "custard," also needs a week, or two, to open up and really start showing the real magic.I made this one with vanilla bean ice cream and it was just okay. Maybe it needs to steep. This is an example of how different flavors really are!
I do find the recipe is an adequate shake and vape but really starts to shine after a week and continues to mature until/through week three. Of course YMMV.
