First prepare the rice. While the rice is cooking, we take care of the stew.
First cut the meat and kimchi into bite-sized pieces. Then fry the meat in oil, add the kimchi and fry together for a few minutes. Meat and kimchi are allowed to burn slightly on the bottom of the pot / pan (do not burn = black!). That adds flavor. Then add water until the meat and kimchi are completely covered and simmer for 30 minutes. Finally add the sesame oil.
Optional: fry the tofu and / or potato pieces and then cook them with them.
If you like to enjoy your stew with a lot of liquid, you should keep the pot closed while simmering and add more water if necessary.
Serve the stew with rice and roasted seaweed leaves.
PS: Old kimchi, i.e. stored / fermented for a long time, is best for stew.
