10 grams (1/3 oz) sectioned scallions
10 grams (1/3 oz) sliced ginger
100 grams (8 tbsp) dry cornstarch
50 grams (3 tbsp) water
1. Cut the fillet into chunks 5 cm (2 inches) long and 4 cm (1.6 inches) wide and mix with 5 g (1/6 oz) of scallions and ginger each, 1 g (1/6 tsp) of salt and 10 g (2 tsp) of cooking wine, and marinate for 10 minutes.
2. Dust the marinated chunks of meat with dry cornstarch.
