Clean beef offal (such as tripe and intestines) thoroughly and blanch in boiling water.
Cut the blanched offal into bite-sized pieces.
Prepare vegetables such as radish, green onion, and garlic.
In a pot, add water, offal, radish, and garlic, and bring to a boil.
Skim off the foam and simmer over medium heat.
When the broth is well flavored, season with salt, pepper, and soy sauce for soup.
Add green onion and simmer briefly.
Serve the finished offal soup in a bowl with rice.
