step 1
Combine a quarter of the onion, half the tomato and half the garlic along with the salt and lime juice and stir to make a rough salsa.
step 2
Heat the oil in a frying pan over a medium heat and add the remaining onion and sauté for about 8 minutes until softened and beginning to brown. Add the remaining garlic and tomatoes and continue to cook for about 5 minutes until the tomatoes have broken down, then add the beef, kimchi, if using, and all of the spices. Cook for about 5 minutes, stirring frequently until the meat is cooked through and has browned in places. Add the ketchup, soy sauce and Worcestershire sauce and continue to cook for 3-4 minutes.
step 3
To serve, use a paper towel to spread a little oil around the surface of a well-seasoned pan. Pack the rice into the bottom of the pan and set over a medium heat on a portable stove at the table. Top with the taco meat, then the cheese, salsa, spring onions, lettuce and egg yolk. When you start to smell popcorn, switch off the heat – that means the rice is toasted nicely. To serve, mix everything well and eat straight from the pan. At the end of the meal, scrape off the crispy rice bits with a wooden spoon.
