Crack two eggs in a mixing bowl and beat them with a manual or an electric beater. Add milk to the eggs and beat the mixture well. Put the mixture aside for a while and start making the coating for your cheese sticks.
Take another small bowl and mix the breadcrumbs and garlic salt in it. You can add other spices like, oregano or Parmesan cheese to make a different taste of the coating you are preparing for your mozzarella sticks.
Take out mozzarella cheese from the packet and cut it into ½ inch wide sticks. The length of your mozzarella sticks will be according to the size of the packet you buy from the market. Normally, a 16 ounces packet will give you about a dozen of cheese sticks but you can vary the number as well by cutting thinner sticks.
Put sufficient cooking oil in a saucepan to deep fry your cheese sticks. Heat the oil to almost 185 degrees on your cooking stove.
Take one cheese stick at a time and dip it into the egg and milk mixture you prepared in the beginning. Then roll the egg-dipped sticks into the breadcrumb mixture. If you want a thicker crust, you can repeat the process twice, re-dipping the cheese sticks in egg and rolling in breadcrumbs once again.
Put the coated cheese sticks into hot oil and fry until they turn golden brown. It should take about 30 seconds.
Remove the mozzarella sticks from oil with a draining pan and put them on paper towel to absorb excess oil on them. Serve with tomato sauce or your favourite dip.
