Broth Preparation

1. Prepare the Pork Bones

In a large pot, combine the pork bones and enough water to cover them. Bring to a boil over high heat for 10 minutes. This helps to remove impurities. After boiling, drain the bones and rinse them under cold water.

2. Make the Broth

In a large pot, add the cleaned pork bones, 4 liters of fresh water, garlic, ginger, and onion. Bring to a boil, then reduce to a simmer. Let it cook for about 12 hours, occasionally checking the water level and adding more water as necessary.

After 12 hours, strain the broth into another pot. Add soy sauce, mirin, and salt to taste. Keep it warm on low heat.

Simmer the pork belly for about 2 hours until tender, turning occasionally. Remove from the pot and let it cool. Once cooled, slice into thin pieces.

Eggs and Noodles Preparation

Bring a pot of water to a boil. Gently add the eggs and boil for 6-7 minutes. Remove and place in an ice bath to stop the cooking. Once cooled, peel the eggs and set aside.
