Tender sesame beef and pepper stir-fry

Method

1. Cut the beef into 5mm-thick slices. Mix the marinade ingredients together in a bowl, add the beef slices, cover and chill for 20 minutes.
2. Dip the beef slices in flour, then in egg, then cover with sesame seeds. Prepare the rest of the ingredients.
3. Heat a wok over a high heat. Swirl the groundnut oil in the wok, add the beef and cook for 1 minute until browned. Remove and set aside. Add the rice wine and the green pepper and stir-fry for 2-3 minutes. Add the stock and bring to a simmer. Season with the soy sauce, sesame oil and the sugar. Stir in the cornflour paste and cook for a minute. Return the beef to the wok, stir and serve.
