Marinate the shrimp in lemon juice for 30 minutes.
Combine flour, cornstarch, and salt in a mixing bowl then mix well.
Add the eggs and milk stir until all the ingredients are well distributed.
Heat a pan and pour-in the cooking oil.
When the oil is hot enough, dip a piece of shrimp in the batter (leave the tail uncovered) then deep-fry until the color of the outer part turns dark yellow and the texture becomes crispy.
Remove from the pan or fryer then place in a plate with paper towel (this will absorb excess oil).
Serve with sweet and sour sauce. Share and enjoy!
