Steep for two to three days.
**Edit: Swapped FA Banana @ 1% for HS Banana @ .75%
I find the HS Banana to provide a more pronounced, more authentic banana accent to the mix than FA Banana. You can use this in the range of .5-.75% depending on how much banana you want coming forward in your mix.**
Not a particularly exotic or developed recipe, but darn delicious! This was inspired after I got a concrete at Freddy's Frozen Custard; banana & butterscotch make for a helluva combo! I have some ideas on different routes to take this idea. This is a first iteration so I may make changes to it but so far I'm vaping through this and loving it.
