Tonkotsu Ramen Recipe (豚骨ラーメンの作り方)

Hello! In this post, I will show you how to make Japanese Tonkotsu Ramen (Pork Bone Soup Ramen) from scratch. Tonkotsu ramen (豚骨ラーメン) originated in Fukuoka on the Kyushu island of Japan. The soup broth is based on pork bones and other ingredients, which are boiled for long hours, and served with ramen noodles that are hard in the center. It is the most popular type of Ramen in Japan as well as Japanese restaurants all over the world. There are many famous Japanese Ramen restaurants that uses mainly Tonkotsu Ramen like Ippudo, Ichiran, and Kaneda-ya.

In my recipe, the ramen broth is made with 100% Tonkotsu Soup (Pork Bone Soup) boiled for about 5 hours. This method of cooking the soup creates more concentrated taste as well as a thicker consistency. The ramen sauce (Tare) is made from mussels and adds umami and dimension. The hand-made ramen noodles were cut thinly, using lesser water content to let the noodles absorb the tonkotsu soup flavours. The main topping is Aburi Chashu (Seared Chashu), which adds smokiness and sweetness to the enjoyment of this ramen.

As always I did not use any MSG in my ramen recipe, however the ramen retains umami and was creamy, comforting and very enjoyable.
