A nectalo is a small, orange colored variety of citrus fruit, very sweet in taste and most resembling a small orange. It is often referred to by it's other name of "Clementine". It was originally thought the origin of the name came from the cross of 2 fruits, the nectarine and the orange. This is false- the name actually was coined by the man who first genetically created the fruit, Francis Nectal. Francis Nectal's wife was named "Clementine" and it is commonly believed that the fruit got it's common nickname from her.
I was at the fruit market the other day and they had a crate of nectalo's for only $5.99!
