I have been plain TFA Peppermint for years and my other long time fav is just a 3 flavor mix with BlackBerry,Peppermint and a tad of menthol. I prefer recipes with 3-4 ingredients but sometimes that doesn't work out..Anyone still do simple single flavor mixes anymore? I get that complex mixes can yield better flavor, but I tend to create coil killers when I start adding bakery and some candies to a mix. Maybe there's a method to the madness that allows complex flavor without crudding up the coil in a day.
