Wikipedia Article About Arracacha on Wikipedia The arracacha is a garden root vegetable originally from the Andes, somewhat intermediate between the carrot and celery. Its starchy taproot is a popular food item in South America, especially in Brazil where it is a major commercial crop. The leaves are similar to parsley, and vary from dark green to purple. The roots resemble fat short carrots, with lustrous off-white skin. The interior may be white, yellow, or purple.
