Take the Roasted Sesame seeds and using a mortar and pestle, grind them up. You can use an electric grinder as well. Set aside.
In a medium pot, add the oil, garlic, ginger and green onions. Saute over medium heat until it fragrant and the onions start to soften. About 3 to 4 minutes. Keep stirring so nothing starts to burn.
Now add the doubanjiang and miso. Keep stirring well so nothing burns. Let this cook together for a couple of minutes. This is where I chop up the dried shiitakes that you saved and add them for additional flavor.
Now add the Sake or Vodka and deglaze. Keep stirring and make sure you mix everything well and cook off the alcohol.
Add the soy sauce and ground sesame seeds. Stir and mix well.
Slowly add the non-dairy milk. Keep stirring to mix everything together. Add salt and pepper to taste.
Lastly, add in the Dashi that you made previously. Bring the mixture to a boil, reduce and let simmer for a couple of minutes. Remove from heat.
I like a smooth broth. Once the broth has cooled a bit, I use an immersion blender to smooth. It's ok if there a few pieces, especially from the mushrooms. If you don't have an immersion blender, you can use a blender or food processor, BUT DO NOT PUT THE BROTH IN HOT. Make sure it has cooled down or the top can shoot off your blender and you will have a mess!
