Clementines are the best citrus fruit, really. Especially the green ones, which might not as sweet as the orange siblings but what they lack in sugar, they more than compensate in flavor. Unluckily, in many places it seems that the only way to get this specie is to grow your own - which is more than possible. That's what I did and look at how lovely they turned out. In the meantime, until your tree grows and gives fruit (somethings between 2-3 years), feel free to get into the spirit by getting yourself a Clementine tee shirt, neck-tie, mug or any other product from the large variety.
