Tonkotsu Chashu Ingredients

Method

Preparation Directions

1

Prepare the Pork Bone Broth

In a large pot, add the pork bones and cover with water. Bring to a boil and then reduce to a simmer. Cook for at least 12 hours, skimming off any impurities that rise to the surface. The longer you simmer, the richer the broth will be.

2

Make the Chashu

Roll the pork belly tightly and tie it with kitchen twine. In a pan, combine soy sauce, mirin, sake, and enough water to cover the pork. Bring to a boil, then add the pork belly. Simmer for about 2 hours, turning occasionally. Once tender, let cool in the liquid, then slice.

3

Prepare the Eggs

Soft boil the eggs by cooking them in boiling water for 6-7 minutes. Once done, place them in an ice bath to stop the cooking. Peel and marinate in a mixture of soy sauce and mirin for at least 30 minutes.

4

Prepare the Kuro Mushrooms

Soak the kuromushrooms in warm water for about 20 minutes until they are rehydrated. Drain and slice them thinly.

5

Cook the Noodles

Cook the premium noodles according to package instructions. Drain and set aside.

6

Assemble the Tonkotsu Chashu

In a bowl, place a serving of noodles, ladle the hot pork bone broth over the noodles. Top with slices of chashu, a halved marinated egg, sliced mushrooms, chopped green onions, and a sheet of roasted seaweed. Season with salt and black pepper to taste.
