Naranjilla or lulo (lat. Solanum quitoense) is a tropical fruit native to the Andes mountains in South America, particularly found in countries like Ecuador and Colombia.
The name "naranjilla" translates to "little orange" in Spanish, a nod to its appearance, although it is not closely related to oranges or other citrus fruits. Instead, it belongs to the nightshade family, which also includes tomatoes, potatoes, and eggplants.
The flavor of naranjilla is unique and often described as a mix between lime and rhubarb or a combination of citrus and pineapple with a hint of earthiness. Naranjilla is used in a variety of culinary applications, particularly in the form of juices, jams, and desserts.
