For the mojo: Stir together the lime juice, cilantro, vinegar, honey, garlic, chiles and some salt and black pepper in a small bowl and let sit at room temperature while you prepare the hash, to allow the flavors to meld.
For the yucca hash: Put the yucca, bay leaf and garlic in a large saucepan and cover with cold water by 2 inches. Sprinkle the water with salt and black pepper. Bring the water to a boil, and then reduce the heat to a simmer. Cook the yucca until just tender, but not falling apart. Drain well in a colander, then transfer to a paper-towel-lined baking sheet to drain again. Discard the garlic and bay leaf.
Heat a large cast-iron pan or griddle over medium-high heat. Add the oil and bacon and cook until the fat is rendered and the bacon is crisp. Remove with a slotted spoon to a paper-towel-lined plate. Add the cumin and onions and cook until soft, about 4 minutes. Add the yucca and cooked bacon and season with salt and pepper. Cook the hash, pressing with a spatula, until the bottom is crisp and dark brown. Turn the yucca pieces using a spatula and repeat pressing and browning until brown and crisp on all sides. Transfer to a platter and drizzle with the lime-cilantro mojo.
