Peel and cut potatoes into long, thin strips.

Combine warm water, sugar, and corn syrup in a large bowl.

Soak the potato strips in the sugar-water mixture for 30 minutes.

In a separate bowl, mix potato starch, flour, and milk until smooth.

Remove potatoes from the water and coat evenly with the potato starch, flour, and milk mixture.

Season the coated potatoes with salt, pepper, paprika, garlic powder, onion powder, and mashed bouillon cube.

Heat lard in a medium pan until fully melted.

Fry the potatoes in the lard for 3 minutes, turning once. Remove and pat dry.

Place the fries in a Ziplock bag and freeze for at least 1 hour.

Heat vegetable oil to 350°F.

Remove fries from the freezer and fry in the oil for 7-10 minutes, or until golden brown and crispy.

Serve hot.
