Had some chocolate mint, might still, as mint has taken over the bed. It did have a chocolaty taste. Are you saying that you put mint leaves on ice cream? Hmmm..... not sure I'd like that. But if I would look up distilling essential oils... oil over ice cream could work.
And as far as pineapple goes... I used to not care for it until I had it glazed and roasted... then it's like give me give me give me.
