Make the batter by beating an egg on a separate bowl. Add water. Mix well. Gradually add flour and cornstarch while mixing. Add salt, paprika, fish sauce, garlic powder, and ground black pepper. Whisk until the texture of the batter smoothens.

Heat oil in a pan. Scoop around ¼ cup of mixture and place it on a saucer or small bowl. Put shrimp on top. Slide the mixture into the pan. Fry until golden brown and crispy. Flip the okoy and do the same to the opposite side. Remove from the pan and place on a plate lined with a paper towel. Perform the same step until the entire mixture is consumed.

Transfer to a serving plate. Serve with dipping sauce. Share and enjoy!
