Two 1-pound blocks part-skim mozzarella, such as Polly-O
Three 8 1/2-ounce bags spicy cheese-flavored snacks, such as Flamin’ Hot® Cheetos®
4 large eggs, lightly beaten
Vegetable oil, for frying
1/2 cup ranch dressing
2 tablespoons Vietnamese hot sauce, such as sriracha.
Watch how to make this recipe.
Special equipment: a 2 1/2-inch-wide heart-shaped cookie cutter and a deep-frying thermometer
Put the unwrapped mozzarella blocks in the freezer for 30 minutes to firm. Meanwhile, pour the cheese-flavored snacks into a food processor and pulse until finely ground. Reserve 1 cup for sprinkling at the end and transfer the rest to a large bowl. Put the eggs in a separate large bowl.
Unwrap the cold blocks of mozzarella and use a long, thin knife to cut them in thirds lengthwise through their narrow sides (like sandwich bread), so you have 6 thinner blocks of mozzarella. Using a 2 1/2-inch-wide heart-shaped cookie cutter, cut out 2 hearts of cheese from each thin block; you should have 12 hearts total. Using the tip end of the heart cutter, cut out a deeper cleave in the top of each cheese heart to make the heart shape more defined. Save the scraps for another use.
Dip each cheese heart in the beaten egg, then toss in the cheese dust until fully coated. Repeat 2 more times to create a very thick coating, then transfer to a baking sheet. Freeze the cheese hearts for at least 1 hour and up to 3 days.
Pour enough oil into a large heavy pot to come 2 inches up the side and attach a deep-frying thermometer to the pot. Heat the oil over medium heat to 350 degrees F. Using a slotted spoon or strainer and working in 3 batches, lower the hearts into the oil and fry until browned at the edges and the cheese is fully melted, about 4 minutes. Lift the hearts from the oil and transfer to paper towels to drain.
Transfer the hearts to a platter and sprinkle with the reserved cheese dust. Pour the ranch dressing into a small serving bowl and pour the hot sauce in the center of the ranch dressing. Drag the tip of a knife straight through the center of the dressing and hot sauce to form a heart shape. Serve the fried hearts while hot with the spicy ranch dipping sauce.
