Heat a large saucepan or pot with the oil until just hot.
Add the ginger slices and fry gently for 1-2 minutes to release the flavour into the oil.
Add the chicken pieces and fry for about 4-5 minutes until browned all over.
Add the spring onion and then the cooking wine and sugar. Let this come to a simmer for 3-4 minutes to burn off the alcohol.
Pour in about 500ml water and again bring to a simmer.
Reduce the heat to low and cover with a lid. Simmer gently for 40 minutes, until the chicken is cooked through.
Add the salt and pepper, fish out and discard the spring onion, then serve
Serve on its own or alongside a small bowl of cooked rice.
Notes
Substitutions & Variations
Add noodles: Serve over cooked wheat noodles for a more substantial soup; add noodles to the bowl, top with hot soup and chicken, finish with sliced spring onion.
Add vegetables: Keep it light — napa cabbage (wombok), halved bok choy, or a handful of bean sprouts work well.
Serving & Storage Suggestions
