Vegan ramen!

The toppings are roasted sweet potato, shiitake, and maitake, shiitake simmered in soy sauce and mirin, and roasted eggplant with sesame. I pretty much tried to follow exactly, the broth was delicious. Not as heavy and creamy as a tonkotsu broth but still had a satisfying body with a fresh flavor.
If I made this again I would:
Probably do a different oil than the shiitake and green onion infused oil. Maybe it's because I didn't use dry shiitake but I don't really see the point of adding an infused oil that uses the same ingredients as the stock and tare. Chilli oil, maybe?
Buy better noodles. I thought it was a waste to buy expensive Sun Noodles and not use the seasoning packets, but the noodles I got instead were pretty disappointing after spending like 3.5 hours making the other components.
Not make the eggplant topping. It tasted good on its own but imo the texture just isn't nice when it's submerged in soup. The shiitake simmered in the tare had too much of the soy sauce flavor as well. Instead of them maybe corn, enoki, or bamboo shoots or something.
Oh yeah also I accidentally boiled the kombu which gave the soup a very slight bitter undertone, would be more careful next time.
