HIC's mellow vanilla is the one I use a lot. I tweaked it a little, lowered the vienna cream and added more vanilla bourbon and marshmallow, maybe by a half a percent each, I think. He also has a "Simply Vanilla" recipe but I've never made that one as posted because it calls for TFA's sweet woodruff flavor, which was always out when I tried to order it, but I've made it without and it's also okay. Good starting points both. Oh, and if you want to play around with any coffees, I suggest starting with one drop at a time. I gave up on coffee because they seem too strong to me, always. The best I've tried is FA's Tiramisu, and that one I can only use at about 0.5 percent.
