Ingredients for vegetable dashi (Japanese soup stock)

Vegetarian Dashi Stock

A critical building block of vegetarian Japanese cooking, this stock is full of naturally-occurring flavor enhancers from kombu seaweed and shiitake mushrooms.  Ideally, the seaweed and mushrooms will soak for many hours, but that isn't essential. A decent stock can be made in a hurry.

Ingredients

  • 15-20 square inches kombu sea vegetable
  • 2-4 dried shiitake mushrooms
  • 4 cups cool water

Instructions

  1. Place a piece of kombu sea vegetable and several dried shiitake mushrooms into the water. For best results, use a glass or ceramic container.

  2. Let this mixture steep for a few hours or overnight in the refrigerator. A long soaking allows the natural glutamates (flavor enhancers) to develop and dissolve into the water.

  3. When ready to make the stock, put the mixture in a pan over medium heat.
  4. Bring it almost to a boil, then reduce the heat slightly to keep it at a low simmer. Keep it at this point for 5 minutes, then turn off the heat.
  5. Let the mixture steep for 5 minutes more, and then strain into a saucepan.
  6. Save the shiitake mushrooms for another use (recipes that call for dashi also often use shiitake mushrooms).  The kombu is often discarded, though there are certainly recipes that use it (Washoku has a one for a kombu relish).
