That looks like a really good recipe. I'm only missing JF Cocoa, but I am thinking "almost" any chocolate will suffice. Specifically a dark chocolate at 0.5%; such as VT Dark Chocolate.
In my experience using FA Tiramisu at 3.5% will overpower the mix even with all the "creamy" flavors counterbalancing it. But, that "might" be desirable for some (depends!). 3.5% is just way too much, overkill, too strong, for my tastes.
I've never used it over 1.5%. Even at 1.5% it's quite strong. It's one of FA's more concentrated flavors. Usually I mix tiramisu between 0.25-0.5% in mixes and as a supporting flavor. As a tiramisu "centric" mix I would go as high as 1.5%.
FWIW FA Tiramisu works excellently at 0.5% with the addition of another coffee flavor. Like FA Cappuccino at 1-1.5%. They balance each other super nicely and bring out a wonderful coffee "richness" in the mix.
FA Vanilla Tahity is a really nice light "tropical" vanilla. It has hints of almond and cherry. At 3% it will make itself known in the mix. Personally I would start lower. But again, YMMV.
If I were mixing that recipe, I would start FA Tiramisu at 1% and Vanilla Tahity between 1.5-2%. I would also start it off minus the FA Jamaica Rum, see how you like it, then add it if desired.
FA Tiramisu from HIC's Notes:
Tiramisu (rightfully) has a reputation as one of FA’s best flavorings. It’s the bold flavor of strong coffee, dark bittersweet chocolate, creamy mascarpone, and a little vanilla cake. It's strong and just lightly sweet. Many people enjoy it standalone at 2% or less. For milder, sweeter tiramisu, use 1% Tiramisu with Vienna Cream, Fresh Cream, perhaps some fruits (raspberry! strawberry! apricot!), maybe Caramel, etc. Or make a sweeter, boozy version with Irish Cream or Rum. Tiramisu makes great coffee and mocha vapes!
Get all your cream, caramel, nut, vanilla, and other flavors to your liking, then add 0.5-1% Tiramisu to make a Starbucks-like coffee/mocha. If you like milder coffee or mocha flavors, try Tiramisu in place of FA Espresso in any recipe, generally at the same percent. Of course add a little Chocolate and/or Cocoa if you want mostly chocolate with just a hint of coffee flavor. Tiramisu can taste quite different with various brands of nic base! The "spicier" your nic base and the more PG you use, the stronger and rougher Tiramisu tastes.
Side note: If you like Tiramisu, SSA Tiramisu is totally worth your money. IMHO it's as excellent as the FA Tiramisu but "different" enough to justify both. They both come from European flavor houses....... meaning they are very excellent IMO.
Hope that helps and good luck!
