This is a very popular Cuban & Miamian appetizer, and great for lunch or just a snack. The various species of malanga (Cuba) or yautia (Puerto Rico), include some of the oldest root tops in the world. It was first cultivated in tropical America, and spread to Africa, and is also grown in the Phillipines. Malanga has more flavor than most other tropical tubers, and has been described as more like nuts than potatoes. Refrigerate for about 3-4 hours.
