Tap the meat with the flat of the knife to tenderise the chicken a little
Cut the chicken into fairly rough pieces
Transfer the pieces to a bowl
Season with salt, white pepper and a splash of Shaoxing wine, then mix
Add the egg whites (egg white is what keeps the meat tender)
Add the bicarbonate of soda, the starch and the flour, then mix
Add water if the mixture is too dry, and more starch if it is too runny
Add a tablespoon of oil and mix
Set aside
