Vegan Cold Tan Tan Udon is a vegan arrangement of the Japanese noodle dish "tan tan men (ramen)" but made with udon noodles in cold, creamy and rich soymilk based spicy sesame broth. The delicious broth is made with kombu dashi based homemade vegan mentsuyu that gives umami and depth to the flavor.* This recipe requires Vegan Mentsuyu made in advance.
First, prepare the Creamy Sesame Broth. In a measuring cup or prep bowl, combine Japanese sesame paste (neri goma) and mentsuyu. Use a whisk to mix well. Then, add soymilk little by little and stir well until well-blended. Transfer to the fridge and keep it chilled until serving.
Next, prepare the Seasoned Tofu Crumbles. Heat up a non-stick surface frying pan at medium high heat. Pour oil then add garlic and ginger. Cook for 1-2 minutes until aromatic.
Add tofu into the pan by crumbling it over the pan then stir for 1-2 minutes. Then, add light soy sauce, sake, mirin, cane sugar, and tobanjan then mix well. Continue to cook (stir occasionally) until tofu becomes golden brown and slightly crispy on the outside. Right before removing from the heat, add sansho pepper powder and toasted sesame oil. Give a quick stir then transfer to a plate or a shallow bowl to cool down. Set it aside until assembling.
Start boiling water in a saucepan or medium pot for cooking udon noodles. Meanwhile, have all the toppings & condiments ready for assembling.
Once water is boiling, add frozen udon noodle blocks and cook for a minute hot (or follow the instructions on the package) until noodles are separated and hot. Once the noodles are done, use a colander to drain and rinse immediately with cold running water to stop cooking and to remove starch. Shake off the excess water.
Prepare an ice bath and transfer the udon noodles to the ice bath to shock them. Drain again and shake off the excess water.
To assemble, place the udon noodles in the bowl then pour the creamy sesame broth. Add the seasoned tofu crumbles, scallions, tomatoes, Japanese mizuna or baby arugula, and rayu. Optionally, use extra condiments & toppings of your choice.
Notes
Neri Goma
Neri goma is Japanese sesame paste that’s made with roasted sesame seeds which gives that rich flavor and the color.
If you can’t find neri goma, subsitute with Chinese sesame paste. Using tahini will not taste the same.
Vegan Mentsuyu
Mentsuyu is concentrated Japanese noodle soup base. It’s such a versatile ingredient that you can make cold noodle dipping sauce and hot noodle soup for udon, somen and soba. You can also use it as multipurpose seasoning for cooking and more.
Important: There is no substitution recommendation of mentsuyu since mentsuyu has all the flavors; savory, sweet, and umami all in one.
Choice of Soymilk
Be sure to use UNSWEETEND & PLAIN soymilk with no vanilla or any flavors.
I use Organic Unsweetened Soymilk from Eden Foods.
Choice of Tofu
For this recipe, super firm tofu (vacuum-sealed package with less water) would be perfect because there’s no need to press the tofu.
Super firm tofu also has a good chewy texture when cooked.
Otherwise, use extra firm tofu and press the tofu for 20 minutes or so to squeeze the excess water prior to cooking.
Sansho Pepper Powder
Sansho peppercorns are unique Japanese pepper with aromatic and almost citrusy flavor along with some numbing effect.
The powder form of sansho pepper is more common in typical Japanese cooking. Also, it’s a common ingredient for Japanese tan-tan noodles (tan-tan men.)
Tobanjan is a spicy condiment/sauce that’s made of fermented chili and broad beans.
It’s a Japanese version of the traditional Chinese ingredient, doubanjiang .
I use Tobanjan called YOUKI Shisen Tobanjan. You can find it at Asian grocery stores and online.
Sugar
I use cane sugar for this recipe and cooking in general.
Using other sweeteners such as agave syrup, maple syrup and coconut sugar etc., will not taste the same.
Choice of Udon Noodles
For this recipe, I recommend using sanuki-style udon which is thick and chewy.
Usually, you can find sanuki-style udon in the freezer section of Asian grocery stores.
Frozen udon is precooked so it takes only a minute or so to be ready.
I use frozen Shirakiku Sanuki-Style Udon.
Mizuna
If you can find Japanese mizuna, I highly recommend using it as a topping. It’s crunchy, refreshing and slightly bitter which is a perfect match with the Vegan Cold Tan-Tan Udon.
You can use baby arugula as a substitute.
Rayu
Rayu is Japanese chili oil which gives an aromatic & spicy kick.
If possible, use the rayu made with sesame oil which is more aromatic.
