Preheat the oil for frying sweet potatoes. In a mixing bowl, combine the first 9 ingredients. Mix well. Shape the mixture into four equal patties. Wrap each pattie with a piece of caul fat, covering the pattie completely. In a skillet over medium-low heat, brown the patties for 2 minutes on each side. After the first 2 minutes add 1/2 cup of water. Flip over the patties and continue to cook for 2 minutes. Add the remaining water and flip over the patties. Continue to cook for an additional 8 minutes, flipping every two minutes. Fry the sweet potatoes until golden brown, about 3 to 4 minutes. Remove the shoestrings from the oil and drain on a paper-lined plate. Season with Essence. Place the burgers in-between the rolls and serve with the french fries.
Combine all ingredients thoroughly and store in an airtight jar or container.
