Citrus japonica
 
The Nagami Kumquat is one of the most popular varieties of kumquat, known for its oval shape and vibrant orange skin. The entire fruit, including the skin, is edible, offering a unique blend of sweet and tart flavors. The skin is sweet, while the flesh is tangy, creating a refreshing contrast. This small citrus fruit is perfect for snacking, preserving, or adding zest to salads, drinks, and desserts.
