Remove the packet of special seasoning oil from the lid.

The “Hakata Tonkotsu Ramen Ippudo Shiro-maru Original Flavor (Cup Noodles)” comes with a packet of “Special Seasoning Oil” attached to the lid. Be sure to set it aside beforehand. The “Special Seasoning Oil” is a lard-based seasoning oil that brings out the deep richness and smoothness of the tonkotsu ramen.

Peel back the lid halfway, and slowly pour boiling water up to the line inside.

The recommended amount of hot water is 280 ml. The package contains freeze-dried wood ear mushrooms, char siu, and green onions, so be sure to slowly pour hot water up to the line marked inside the cup. The restaurant’s signature char siu was developed through trial and error to ensure it could be authentically recreated in a cup noodle.

Warm the special seasoning oil on top of the lid

The cooking time is 3 minutes. Let’s wait while warming the special seasoning oil on the lid. According to the developer, cooking for the full 3 minutes will result in noodles that are slightly on the firm side, but they personally recommended cooking for about 2 minutes and 30 seconds for a firmer texture.

After 3 minutes with the lid on, add the special seasoning oil, mix well, and it's ready.

To finish, add the special seasoned oil that you’ve been keeping warm, stir everything well, and it’s ready to serve.

The soup has a smooth, creamy mouthfeel, infused with the rich depth of pork bone broth and packed with umami. It clings perfectly to the thin noodles, and the soup’s flavor really brings out the noodles’ own umami. Cooked for 3 minutes, the thin noodles had a firm, al dente texture with a pleasant mouthfeel—a classic, authentic texture typical of tonkotsu ramen. The chashu was seasoned with a subtle sweet-and-spicy flavor, and the crunchy wood ear mushrooms added a nice contrast.
