Stir the cornstarch and water together in a small bowl.
1 tbsp cornstarch
Lay an eggroll wrapper out on a flat, clean surface, so that it looks like a diamond with a point facing you.
18 eggroll wrappers
Using your finger, spread a tiny bit of the cornstarch slurry out onto the edges of the wrapper.
Spread 1/2 tbsp of the potatoes out in the corner facing you. Top that with the same amount of stuffing, and a few pieces of turkey.
1 lb cooked turkey, 2 cups mashed potatoes, 2 cups cooked stuffing
Lift the bottom corner of the wrapper up, and fold it over the filling without folding it completely in half. Fold both outside corner in so that they overlap. Begin rolling the eggroll, away from you, tucking the edges in as you go. Brush a bit more slurry over the remaining top corner, or tip. Finish the eggroll, and brush a tiny bit more slurry over the seal. Lay the finished roll on a plate or other surface. Repeat until all the eggrolls are done.
Fill a dutch oven, or cast iron skillet, with about 3 inches of oil. Heat the oil to 350 degrees. When the oil's hot, add the eggrolls in batches of 3-4. Fry them, turning occassionally, about 2 minutes or until they're golden brown.
Remove the eggrolls from the oil with tongs and transfer them to a paper towl lined plate to soak up any excess oil, and cool slightly.
Serve the eggrolls warm with the cool cranberry dipping sauce, and enjoy!
