Ssamjang
This quick, tangy Korean sauce of soybean paste, chilli paste and mirin is perfect with bulgogi or any barbecued meat
In a shallow dish, combine the beef, sugar and pear (if using) thoroughly, and leave to sit for 30 mins at room temperature. Meanwhile, in a large bowl, mix the soy sauce, sesame oil, 1 tbsp of the vegetable oil, the garlic, ginger and sesame seeds to make a marinade, and set aside.
When the beef is ready, squeeze out any excess sugary liquid, then add the beef to the marinade. Toss to coat, cover and marinate at room temperature for 30 mins. Can be marinated for longer, or left overnight in the fridge.
In a large frying pan or wok, heat the remaining vegetable oil over a medium heat. Add the onion and cook for 6-8 mins until softened. Add the mushrooms and carrots, and cook for 5 mins until slightly softened. Raise the heat to medium-high, add the beef and marinade, and cook for 4-5 mins, stirring occasionally, until the meat is browned. Transfer to a platter and sprinkle with the chives and sesame seeds.
