In a small bowl, combine white vinegar, salt and sugar. Soak the shallot and garlic for 15 minutes.
Slice cremini into thin slices. For king oyster mushrooms, slice them lengthwise and then into matchsticks.
In a medium pot, insert a steamer basket. Steam the mushrooms for 15 minutes or until they reduce half in size.
Shave the carrot into thin ribbons (or cut it into matchstick, you choose)
Once the mushrooms cool down, remove the shallots and garlic from the vinegar and combine them with the mushroom and carrot in a mixing bowl.
To make the dressing, add soy sauce and sesame oil into the vinegar and whisk until everything combines.
Add the dressing into the mushroom mixture and toss thoroughly.
Sprinkle with herbs, fried shallots and peanuts.
