Peel the potatoes. In a large mixing bowl, combine sugar, corn syrup, and hot water. Make sure the sugar is dissolved. Using a french fry slicer, cut the peeled potatoes into shoestrings. The potatoes should be 1/4" x 1/4" in thickness, and about 4" to 6" long. (You can do this with a knife, but it is alot of work).
Place the shoestringed potatoes into the bowl of sugar-water, and refrigerate. Let them soak about 30 minutes.
While they're soaking, pack the shortening into the deep fryer. Crank up the temperature to "full". The shortening has to pre-heat for a very long time. It will eventually liquify. After it has liquified and is at least 375°, drain the potatoes and dump them into the fryer. (be careful, it will be ferocious).
After 1 to 1 1/2 minutes, remove the potatoes and place them on a paper towel lined plate. Let them cool 8 to 10 minutes in the refrigerator.
While they're cooling, add the lard or beef drippings to the hot Crisco®. Again, crank the temperature to full. Stir in the lard as it melts into the oil. It will blend inches.
After the deep fryer is reheated to 375°-400°, add the potatoes and deep fry again. This time for 5-7 minutes until golden brown. Remove and place in a large bowl.
Sprinkle generously with salt, then "toss" the fries to mix the salt evenly.
Serve hot, serve immediately, and enjoy! Depending upon the size of the potatoes, this recipe make about 2 medium sized fries.
Special Notes: If you want more fries, double the recipe---but DON'T double the cooking oil. Just cook them in shifts, adding about 1/4 cup more Crisco® and 1 tablespoon lard for the second batch.
