Actually, I've never tasted Vaseline, but my first attempt at DIY e-liquid has an oily taste that ruins it. My recipe was 5 parts PG, 2 parts VG, and 4 parts cinnamon extract. The cinnamon comes through just fine, but the finishing flavor tastes the way lotion smells. I'm guessing that the offending flavor is either PG or VG, but I don't know which one to reduce or eliminate. I'd prefer not having to waste a bunch of liquid by experimenting. Does this sound familiar to anyone? Any suggestions?
