Make sure the prepared mac and cheese is cold before rolling it into balls. This helps it hold its shape better during frying. Freezing the mac and cheese balls at various stages (setting and after breading) helps them retain their shape and prevents the cheese from oozing out during frying. Use a candy thermometer or deep fryer thermometer to ensure the oil reaches and maintains the correct temperature of 360°F (182°C) for frying. Feel free to customize the seasoning in the flour mixture and experiment with different types of breadcrumbs for added flavor and texture. Serve the mac and cheese balls immediately after frying while they are still hot and crispy for the best eating experience.
