How many times have you heard the phrase “China orange”? Well, oranges from China do exist and are better known by the name of Kumquat.

The Kumquat, originally from China, is consumed whole and its skin is edible, a little sweet, however, the inside is more bitter with an acid point.

In fact, there are certain varieties of which only the skin is consumed. In the Iberian Peninsula, it is harvested during the months of January and February as it changes from green to orange. And the person responsible for introducing this fruit in Europe was the English botanist Robert Fortune in the mid-nineteenth century and called it Fortunella Margarita.

Also, the skin of these foods is fleshy, thin and in most species, edible. The outer layer is usually somewhat spicy, while the inner layer is sweet. The pulp is not too fleshy or juicy. It is found in acidic fruits such as orange, lime or lemon. In addition, it contains small green and white seeds inside. They ripen very slowly while a color change is observed.
