Based off DIYorDIE's recipe so credit goes to him. I felt the strawberry needed a kick up the arse so I added some FA Strawberry and upped the TPA Strawberry Ripe a tad, lowered TPA Bavarian Cream a touch (Little too much custard vibes for me), Lowered VBIC (Too much vanilla spice for me), raised CAP Milkshake and lastly, added some milk in the form of Cream (Milky Undertone) (PG) (OoO).
May still further reduce or even omit Bavarian cream altogether as I’m still getting a little too much custard notes for my liking, still unclear how important it is to the recipe but when I think of milkshake, custard does not spring to mind. I may also still play with Strawberry ratios and maybe try other strawberries, not sure yet.
Update: Getting even better with age and Bavarian isn't as prominent as it steeps and is more of a compliment, might still try slightly lower in next mix just to see but finding this very yummy as is.
