Marinate boneless Chicken cubes ( I used Chicken Breast) with Salt, Paprika, Ginger Garlic paste, Vinegar, Buttermilk and Hot Sauce for a few hours or overnight refrigerated best for tender juicy chicken.To Make Buttermilk,Mix 1 Tsp plain Vinegar or Lemon juice to room temperature 1/4 Cup Milk. Mix well and let it rest for 5-10mins till curdles. Buttermilk is ready to use. Or you can make it by mixing 2 Tbsp plain Yogurt with 2 Tbsp Water like me. After marination, add 1 Egg and Mix Well.
In a separate bowl, make a Dry Coating by mixing All purpose flour, Corn Flour, Salt, Garlic Powder, Onion Powder, Paprika, Black Pepper powder, Baking powder and Oregano. MIx well.
Dredge the Chicken pieces with this flour mix. Keep them aside in a plate.
Pour some Ice Cold Water to the bowl with the chicken marinade. Mix Well. Only use Ice Cold Water for best results. The colder the crispy the coating.
Dip the floured chicken pieces in this ice water and dredge them again the flour mix. Press the coating to the chicken pieces and shake off the excess. Repeat this till the flour stick to the chicken like flakes.
Deep fry immediately in Hot Oil on medium heat. Do not let them get dry else the coating gets dried. Keep Stirring for even color. Drain them out once they are golden on both sides.
Drain them on a cooling rack lined below with tissues instead of directly placing on tissues to maintain crispiness. Directly placing on tissues make them soggy after some time.
Serve them hot with Ketchup. The color of the chicken gets deeper once they cool and rest for sometime.
