http://www.seedtosupper.com/persimmons.html and you can get much more interesting facts on persimmons than mine.
For this recipe, 1 cup of fully ripened persimmon pulp was used. My taste test on this is that I don't really taste the persimmons in it. I taste more of the oatmeal and spices than persimmons in it.
Perhaps, cutting down on the oatmeal entirely or measure down to 2/3 or 1/2 or 3/4 Cup would do.
Only testing would tell. But it is a good recipe to start my adventure with baking with HACHIYA persimmons.
1 tsp Vanilla
3 Shakes of Chili Pepper Flakes
a Couple of shakes of Lemon Zest ... about 1/8 tsp but could have used 1 tsp of fresh lemon zest.
