I believe the OP acknowledged that in their original post. I think they were hoping more for potential substitutions.
Welcome to the life of DIY. I have over 220 flavors now (roughly 16 months of recipe collecting) and I still can barely go a day without finding another one I "have" to have!
Yes; Banana - TFA, Ripe Banana - TFA, and Banana Cream - TFA, are all different.
The way they taste
to me :
Ripe Banana - This is the truest banana "fruit" flavor to me. Meaning this tastes the closest to picking up a deep yellow banana, peeling back the peel, and taking a bite. It can go laughy-taffy (candy-like) on you if you use too much. More "ripe" than "green." I personally do not understand all the "it's really strong" cautions you may frequently read; but that could be
my taste buds too. I
DO believe all the cautions about this being a plastic cracker. It has eaten more syringes than any other flavor for me.
Banana - This is the "noncommittal" banana. Good for a mixer where you want banana notes in the background but that is where you want to keep it; in the background. For me this is the "let's be friends" banana option. It is never going to crawl in to bed with you but it is never going to tell you to "F" off either.
Banana Cream - Think store-bought banana cream pie without the crust. The kind where the artificial whipping cream mutes the banana flavoring. Now dial those thoughts back to the strength you are now remembering them (pretty weak). This is Banana Cream.
This is a nice flavor when you want a hint of banana (or cream for that matter). Nice when you want just a hint, or for filling/rounding out other bananas.
A 4th TFA banana that hasn't been mentioned is Bananas Foster. This is one I haven't tried yet so I can't give you
my perception of it. It is supposed to be a more complex "banana" with added notes of ice cream/custard, caramelized sugar/brown sugar, and cinnamon. "Banana" strength somewhere between Banana and Banana Cream. It has also been getting more attention recently over on the TFA threads; enough to cause me to buy a sample size. I just haven't made the time to work with it yet.
So; what can you sub Banana - TFA with? Here are my non-answers:
It depends on the recipe and how the banana is supposed to fit in; a "tropical drink" recipe is going to be different from a "banana bread" or "PB&J Sandwich" recipe.
I personally would make up a 3-5mL single flavor tester of each of the flavors I was considering at 4 to 5%. Give them 24 hours to rest (with 1-2 hours cap off). Then do a side-by-side taste comparison. You are not looking for your "ideal" percentage here; but how one compares to the other for strength and taste. My guess is that none of them will be stellar for you; but you will be able to see how they differ and may compliment one another.
THEN: P e r h a p s, I might look at 3% Ripe Banana alone, or 2% Ripe Banana + 2% Banana cream. Again; it depends on how it works into the recipe. AND THIS IS
ME.
Like
@Sugar_and_Spice said; best to start off at lower percentages and add if needed.
I haven't tried any other manufacturer's bananas to date so I can't speak to other options outside TFA.
Keep us informed on how your search goes.
Cheers!
