In a mixing bowl, you must break an egg in the beginning and then pour soda water into this bowl. Stir both of them well together. You can use a hand whisk or a fork for the purpose.
Now take another bowl and combine the corn flour with flour. Then you must transfer the egg mixture to this flour mixture and mix to combine.
Your batter is ready. Now it's time for you to prepare the shrimp. Bring the shrimp and season it using the mandatory seasonings which include freshly grounded black pepper and salt.
Now drizzle the flour tempura batter on the marinated shrimp. Use a spoon or spatula to mix so that the whole shrimp is well coated with the batter.
Bring a large-sized cooking skillet and pour oil in it for frying. Bring the battered shrimp and put it in the heated oil. Continue frying the shrimp for a few minutes so that they will get crispy by the end of the frying.
Drain the oil by using paper towels and put the cooked shrimp aside.
