When the yuca is tender, cook it for 15 to 20 minutes over medium low heat after covering it with water, adding salt, and bringing it to a boil.
The yuca should be taken out of the water and dried with paper towels. The cooked yuca should be cut into 1/2-inch strips.
Get enough vegetable oil in a big frying pan to heat it to 350 degrees. Place the yuca carefully into the heating oil once it is hot. Fried them for 6 to 8 minutes, or until golden brown on both sides.
Using a slotted spoon, remove the yuca pieces from the oil and place them on paper towels to drain. Add salt and then serve.
