So far it has been, take note of what I have, come up with an idea, take caps off flavors I think would work, do a quick around the nose smell to get the concentration level, tone and body, then completely friggin' wing a recipe and see what happens. ;)
What are your top five flavors from them? Anything to avoid? So far I love their pear and peach.but hate the boysenberry
Sweet cream has acetoin and AP kind of smells and tastes like corn chips instead of bread. So far I dig TFA on the whole, really. Those are my biggest complaints.
Cinnamon Natural swings above its weight in taste to me at least, but YMMV. I'd just advise stepping it down a bit in mixes.
(Not OP.)
I first tried the boysenberry at 10% in a mix, it made my tongue numb. I have since seen it recomended at 1% but I havent been able to make it work yet either.
