1. Cut each salad onion in half and then cut lengthways into quarters to give thin strips about 10cm long. Mix in the chives, gently keeping all the strips parallel.
2. Whisk the flour, soy sauce, pepper and 125ml water together to give a smooth batter.
3. Combine ¼ of the green salad onion mix with ¼ batter, trying to keep all the pieces parallel. Heat a little oil in a frying pan, and fry the mixture, spreading it out to give a rough rectangle of approximately 10 x 14cm. Cook for 2 minutes, turning halfway through.
Repeat to make 4 pancakes.
4.Meanwhile, mix all the sauce ingredients together, and serve with the pancakes.
