How to Make It
Heat oil in a large, high-sided skillet or saucepan over medium to 375°F, about 10 minutes.
While oil heats, whisk together jelly, vinegar, red pepper, mustard, and 1/2 teaspoon of the salt in a small bowl until smooth. Set aside.
Place cornflakes in a large ziplock plastic freezer bag. Seal bag, and crush cornflakes until they form a coarse meal. Transfer crushed cornflakes to a shallow baking dish or pie pan. Stir in remaining 1 1/2 teaspoons salt. Place flour in a second shallow dish. Whisk together eggs and milk in a third shallow dish.
Roll 6 of the cheese sticks in flour. Dredge in egg mixture, and place in cornflakes mixture, pressing to adhere. Carefully place coated cheese sticks in hot oil. Fry until golden brown, 30 to 45 seconds. Using a flat slotted spatula, transfer fried cheese sticks to a wire rack or parchment paper-lined baking sheet. Repeat procedure twice with remaining 12 cheese sticks. Serve with jelly mixture.
