Personally, I have found the Peanut Butter Fruit to taste very much like peanut butter.
I have a tree growing in my garden, and it had flowers, but they fell off and the fruit did not set; so I tasted the fallen flowers, and they tasted to me like peanut butter too!
It is great you are going to Borneo
I went to a talk at my local Fruit Club by a man who lives in Far North Queensland, but who has spent time in Borneo, and he has brought 60 varieties of Borneo fruit to Australia.
I would love to try the Red Durian that grows there. Have you tried it before?
I hope you have a Wonderful time in Borneo, and please keep us posted about the fruits there
Wishing you a Beautiful Day
Love and Peaches,
