There is a vegan restaurant at Tokyo main station called T’s Tantan. They have this amazing Japanese tantan soup that makes me get on a train through half the city, walk forever through the giant station and even buy a ticket for a train I don’t take, to get to the area where the restaurant is.

And every time again I come to the conclusion that this soup is worth the effort.

They were so kind to draw the ingredients on the wall, so I managed to create a tantan soup recipe at home very similar to the one at T’s Tantan. Since 2017 I have improved my recipe, I added chili oil and roasted the bok choy, also I have made the process faster and easier.

Mirin is an ingredient that maybe not everyone knows, it is a sweet Japanese rice wine mainly used for cooking.

Miso Shiro is a mild soy paste that contains a lot of beneficial bacteria, which would be destroyed when boiling it. That’ s why it only goes into the soup once it’s not boiling anymore.

Tahini is a ground sesame paste, you can grind it yourself in a mortar, which is what I did when I started making this soup, but it is so much work and so I just buy it now.

Tantan men, as this soup is called in Japanese, was inspired by the Chinese dish dandan noodles which I once tried in a Szechuan restaurant in Hamburg and was almost unable to finish it because it was so spicy!

The Japanese version is not that spicy, but feel free to add as much chili and chili oil as you like 🙂

    So similar to ts tan tan in Tokyo station – great job and thanks so much for tweaking as you go we’ve been following along. Roasting/grilling the pak choi is a great idea, worked well.
