Sift together the flour, cornstarch, baking soda, baking powder, and salt to ensure a smooth mixture.
Gradually add the water, mixing well to form a thick batter with a smooth consistency.
Dip your fish or chicken pieces into the batter, ensuring they are evenly coated for that perfect crunch.
Deep fry the coated pieces until they are golden brown and crispy on the outside while remaining tender and juicy on the inside.
