1. Place chicken in a large pot and add water to cover. Cover pot and bring to a boil. Reduce heat to a gentle boil and cook for about 10~15min. Remove the chicken and let it cool to room temperature.
2. Put the boiled chicken into your food processor and process until it is roughly chopped. Transfer to a medium bowl.
3. Add the ingredient A to season and knead the mixture until it becomes smooth and elastic.
4. Shape the mixture into small balls, about 2.5cm (1 inch) in diameter. Heat enough oil in a deep fry pan over medium heat. Deep-fry the chicken balls until nicely golden brown on all sides (as they are already cooked, no need to over-fry them). Transfer them to a plate lined with paper towels to drain the excess oil.
Serve hot with ketchup, mayonnaise or mustard as you like!
