I understand a whole lot about myself since I started reading you. I am those who find coriander's smell better than taste. I also dislike the taste of melons and cucumbers. To me, they smell like uncooked pumpkins and boy do I hate pumpkins. Lol.
But seriously, never knew it has to do with genetics. I have always blamed my tastebuds. This is because I have trained them to like stuff they disliked like sweet potatoes. I guess I assumed I can train them to like what I don't!
Thank you for sharing as always :)
