Then add in your chicken and,a bowl of water and black pepper and don’t forget your sauces. I normally prepared my sauces in advance and ready mixed it up together.Leave it about 15minutes with your wok closed and low medium heat. Then add Your pineapple 2-3 minutes before you done. I add it last because I want the sweet taste of pineapple still taste fresh. Always tasted for the taste of u like or not u can always adjusted it.Once done ready to serve.
