Finding juices you like is a journey for sure. My only suggestion is try lots of tobaccos because you may be surprised what you like (I ended up liking Desert Ship from FSUSA as an analog alike - a Turkish American blend - surprise to me) and cocoa or chocolate added to tobacco (most US cigs have cocoa in them). And for food flavors, start with things you like in real life. And remember to smell the vapor - your tongue can only sense sweet, salty, sour, bitter and umami (msg)
Some juice's I like (and I use 20% or less Vg for cartos, or the WOW juices) - Vapor4Life WOWbacco which is a cocoa tobacco that's light on the tobacco (in the WOW tobacco shop sampler) and Vapor4Life WOW vanilla (sharp edged w/ nicotine and quite sweet like cotton candy). Gourmet Vapor vanillarum (vanilla w/ caramel and rum) and sign up so you get their sale emails (infrequent huge sales). For dripping I like the FreedomSmokeUSA 50/50 juices Hopscotch (like Honey and Butterscotch to me) and Voodoo (weird vaguely fruit vaguely cinnamon? aromatic but light), Velvet Vapors Vanilla Almond Tobacco and Raspberry Gingerale.
