The Marumi Kumquat is a small citrus fruit that is often eaten whole, as the skin is sweet and the pulp is tart. Known for its many health benefits, the Marumi Kumquat is packed with vitamin C, fiber, and antioxidants. Although the Marumi Kumquat is a unique fruit in its own right, there are several synonyms that can describe it. These include the Nagami Kumquat, which is slightly more sour than the Marumi, as well as the Citrus japonica, Fortunella japonica, or Fortunella margarita. Regardless of the name you use, there is no denying that the Marumi Kumquat is a delicious and healthy addition to any plate.
