How to Make It
In a large saucepan of lightly salted boiling water, cook the yuca for 10 minutes. Add 1 cup of cold water to the saucepan and bring back to a boil. (The cold water tenderizes the yuca.) Continue to cook the yuca until tender, about 5 minutes longer. Drain and refresh under cold running water; drain again and pat thoroughly dry. Check the yuca for stringy fibers and pull out them out.
In a deep-fryer or medium saucepan, heat 2 inches of oil to 350°. Divide the yuca into 4 batches and fry each batch until golden brown, 2 to 4 minutes. Using a slotted spoon, transfer the yuca to paper towels to drain. Sprinkle with salt and serve at once.
