Citrus limettioides Tanaka
This citrus fruit has the same shape of oranges, but the thin skin and the juicy pulp are generally lighter in color. Sometimes more acidic, sometimes sweeter, the fruit is the main ingredient of a prized version of caipirinha, either mixed with cachaça, vodka or sake. As well as other citrus fruit, it is rich in vitamin C and, according to folk medicine, it helps digestion.
