Pro Tips for Perfect Results
Freezing Trick: If cheese leaks despite double coating, freeze the breaded sticks for 15-20 minutes before frying. This firms up the cheese and gives the coating extra time to set.Oil Selection: Peanut oil is ideal for its high smoke point and neutral flavor, but canola, vegetable, or sunflower oil works well, too.Batch Size: Never crowd the fryer. Cook only 2-3 sticks to maintain proper oil temperature.Testing Doneness: When tapped gently, the coating should be deep golden brown and sound hollow.
