Korean oxtail soup (sokkoritang)

How long does it take to make Korean oxtail soup? Not long if the oxtail is already tender. I cooked the oxtail overnight in the slow cooker. Well, 95% cooked anyway. The radish and chili sauce were added the following day.

Aside from the obvious convenience of using a slow cooker, precooking the oxtail and allowing it to cool has another benefit. Oxtail is fatty and a lot of the fat liquefies into the broth during cooking. If that worries you, here’s the thing.

By chilling the broth in the fridge, the fat floats to the surface and hardens. You can easily remove that layer of fat before finishing the soup.

If the fat is not an issue with you, ditch the chilling part. Without removing the oxtail from the slow cooker, add the radish, scallions and chili sauce during the last two to three hours.

To complete the soup

• ▢ ½ cup thinly sliced scallions

For the chili sauce

• ▢ 1 teaspoon minced garlic
• ▢ 2 tablespoons soy sauce
• ▢ 2 tablespoons chili flakes
• ▢ 1 tablespoon gochujang (Korean chili paste)

Instructions

 

• Rinse the oxtail well. Place in a pot. Cover with water. Boil for 10 minutes, drain, discard the water and rinse the oxtail again to remove impurities.
• Place the cleaned oxtail in the slow cooker. Add the garlic, scallions, salt and peppercorns. Set the cooker to low and cook the oxtail for eight hours.
• Scoop out the oxtail and transfer to a container.
• Strain the bone broth into another container.
• Chill the oxtail and broth in the fridge overnight or up to a day.
• Scrape off the layer of fat that forms on the surface of the broth and discard.
• Pour the broth into a pot. Add the oxtail and radish. Simmer until the oxtail meat is tender and the radish is soft.
• While the oxtail and radish simmer, make the chili sauce by stirring together all the ingredients.
• When the oxtail and radish are done, add the scallions.
• Stir in the prepared chili sauce, a tablespoon at a time, until you get the flavor balance that you like.
• Ladle the soup into bowls, serve with the remaining chili sauce on the side, and enjoy!
