It's a very simple recipe for those who can't buy plenty of concentrates .
I know that the cinnamon danish is overflavoring but it's the only way for few concentrates and simple recipe .
If you have problem to find the Stark Flavor (Apple) (FA) , change it with fuji (fa) at 0,5-0.7% .
If you want , you can pull out the walnut .
You can put butterscotch ripple (FW) 0.8-1%
i strongly recommend 1 drop/30ml from Clove (fa) .
Not sure I get the "you can pull out the walnut"
There does not seem to be walnut in the recipe.
I would not mind it if there was as I have tons of Walnut FA...
