A cute oval mini orange but also an ornamental plant (Citrofortunella mitis) and a very nutritive fruit. I have been eating a bunch of these this morning and apart from knowing that is used in Chinese Medicine, I was curious to know more about this tiny fruit packed with Vitamin C.
This link at Fruits.info explains the lineage and benefits better than I can.
For all the fruitaholics, having also bumped into other generous blogs with this tag, some tempting recipes came to sight that I had to share:
