I've got to politely disagree with
@Adam harris on his TFA assessment. While I don't doubt that he gets a "peppery" note, and have read a couple of similar comments here and there, I would not say that "most" do. I would be more inclined to say "a few do."
If you check out ECF's TFA, and TFA Recipes, threads you will see it used frequently. I also like to use vendor websites like Bull City Flavors who display customer comments/ratings for their flavors. While this is far from all-inclusive, or scientific, it still provides
some feedback. Bull City shows 17 ratings for TFA's VBIC and two are 4/5 while the remaining fifteen are all 5/5. To me (at least) this is another indicator that "most" are not finding this "peppery."
I find that BOTH TFA and CAP VBIC have their usefulness in my kit. Both offer a good vanilla ice cream taste, while the CAP version offers a deeper "richness" and heavier/thicker "mouth-feel". Of course, as with any flavor, your mileage may vary.
I also recommend
with any flavor that is new to you;
buy small samples first! Find out if you like it
before you commit to a 1oz., 4oz., or larger investment.
