Add water, garlic cloves and bay leaves to a pot of water and bring to a boil.
While water is boiling, peel yucca root and julienne cut it into fries.
When water is boiling, add yucca root and cook for 15 minutes. Strain and set aside.
In a separate pot, add duck fat and heat to 375° F.
When fat is hot enough, add yucca fries careful not to burn yourself.
Fry yucca for about 10 minutes or long enough to get a light golden brown.
Remove fries from pot and place on a paper towel.
Add salt immediately, and serve while hot. Don't be surprised if these go fast. These went so fast when I was making them, that I didn't even have time to get a picture of the finished product.
