The other day a work friend gave me some oranges from her garden. At the time she told me they were Clementines, but when I cut them in half I was surprised to find the flesh inside was a dark orange/red colour. When juiced up the 'orange' juice was dark red! (I've got my little helper doing the juicing in this photo shot!).
So I guess the orange must be a type of 'Blood' orange. The juice was absolutely delicious. Shame there was only enough for a couple of glasses!
