TFA Root Beer Float 6-10%
TFA Vanilla Swirl 2%
TFA Sweet Cream 1%
(These two can be used in many other recipes)
or just use Tasty Puff Rasta Root Beer at 6%
Until you find which flavors and brands you like, this can be a never ending list.
As an example:
Some like CAP Creamy Yogurt best
Some like CAP Greek Yogurt best
Some like FW Yogurt best
Some like FA Yogurt best
Think I missed a couple
Many of the Yogurts have a sour note that some like, but some like the sweeter versions.
It gets worse from here when you consider the number of different Strawberry flavors/brands.
But INW Shisha Strawberry is one of the favorites used around here, and mine too.
Kinda depends on what flavors you like, Fruits, Bakery, Cinnamon, Yogurts, Custards, Cheesecakes, etc.
Don't start with LA flavorings.
CAP & TFA/TPA are probably the more forgiving brands for beginners.
FA & INW use lower amounts typically, than most of the other brands.
FW varies in amounts needed, but they do have some good flavors, and are pretty cheap.
