Know your Arracacha


Know your Arracacha - Introduction

  • The arracacha, Arracacia xanthorriza, 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.

Know your Arracacha - Common names

  • The name arracacha (or racacha) was borrowed into Spanish from Quechua, and is used in the Andean region. 
  • The plant is also called: 
    • apio criollo ("Creole celery") in Venezuela.
    • zanahoria blanca ("white carrot") in Ecuador.
    • virraca in Peru.
    • mandioquinha ("little cassava") or batata-baroa in Brazil. 
  • It is sometimes called white carrot in English, but that name properly belongs to white varieties of the common carrot.

Know your Arracacha - Cultivation

  • The plant is very susceptible to viruses and is slow to mature (10–12 months), but requires much less fertilizer input than the potato; its cultivation can be very lucrative. 
  • It was imported into Brazil in the 19th century and has been grown commercially since the 1960s. 
  • Brazilian crop improvement programs have developed varieties that grow in seven months.
  • The harvest season in the Southern Hemisphere spans from January to September. 
  • The roots must be picked promptly lest they become woody. 
  • They have a short shelf life and must reach consumers within a week of harvest. 
  • The plant grows west of the Andes at altitudes varying from 200 m to 3600 m, but optimally between 1800 and 2500 m. 
  • It is frequently grown with other crops such as maize, beans, and coffee.

Know your Arracacha - Cuisine

Arracacha

  • Fresh arracachas keep in the refrigerator for 2 to 3 weeks. 
  • The young stems can be eaten cooked or in salads, and the leaves can be fed to livestock.
  • The most important part is the starchy root. 
  • It cannot be eaten raw, but when cooked it develops a distinctive flavour and aroma that have been described as "a delicate blend of celery, cabbage and roast chestnuts".
  • The boiled root has about the same uses as boiled potatoes, including side dishes, purées, dumplings and gnocchi, pastries, etc., with the advantage of its flavour and (depending on the variety) its intense colour. 
  • In the Andes region it is made into fried chips, biscuits, and coarse flour. 
  • Because it is highly digestible (due to the small size of its starch grains), purées and soups made from it are considered excellent for babies and children.

Arracacha Soup

  • To make arracacha soup, peel just over a pound of arracacha and boil in 6 cups of stock until soft. 
  • Blend until smooth and set aside. 
  • Sauté 2 large onions and 2 large tomatoes. 
  • Season to taste and add to the puree. 
  • Add 2 chopped scallions for garnish.

Know your Arracacha - Nutrition

  • 100 grams of arracacha provide about 100 calories (26 g of dry matter, 23 g being carbohydrate, and less than 1 g of protein). The plant is rich in calcium (four times as much as potatoes).
  • The yellow cultivar contains substantial amounts of carotenoid pigments, precursors to vitamin A, to the point that excessive consumption of arracachas may cause yellowing of the skin (a condition that is not considered to be harmful).
