I didn't buy it because of the fruit either but rather because I liked the plant. But as a citrus addict one
has to taste the fruit also!
The bitter taste reminded me of the taste of the skin of the parts of a grapefruit (I hope you understand what I mean, I don't know the english name of it
).
I also seem to recognise the bitter taste of some drinks, like Campari, that I believe are made of chinotto...
If you say the fruit normally isn't dry, I hope I can have better fruit in the future!
