Prepare the Mozzarella
Cut the mozzarella into 2–3cm sticks and pat dry. Set aside.
Make the Batter
In a bowl, whisk together flour, milk, egg and a pinch of salt until smooth.
Crumb the Cheese
Coat each mozzarella stick in flour.
Dip into the batter, letting excess drip off.
Roll in panko until fully coated.
For extra hold, repeat the batter + panko step.
Freeze for 30–45 minutes — this makes frying much easier.
Make the Chilli Oil
Combine chilli flakes, five spice, salt and minced garlic in a heat-safe bowl.
Heat oil in a small saucepan until shimmering (170–180 °C). Carefully pour hot oil over the spices. Set aside to cool.
Make the Coriander Ranch
In a bowl, mix spring onion, coriander, mayo, sour cream, buttermilk, garlic and salt until smooth. Chill while you fry.
Fry the Mozzarella Sticks
Heat oil to 170–180 °C. Fry frozen mozzarella sticks 3–4 at a time for 1–2 minutes until golden.
Drain on paper towel.
Serve
Drizzle or spoon chilli oil over the hot sticks. Serve immediately with coriander ranch.
