Ingredients

  • 2 cups kombu dashi soak a piece of kombu in 2 cups of water overnight
  • 1 teaspoon vegetable dashi or vegetable bouillon
  • 2 tablespoons gluten free soy sauce or tamari
  • 1 teaspoon sugar I used coconut sugar
  • 1/2 teaspoon salt
  • 2 cups Japanese short grain white rice my grandma likes this brand, but any brand will do
  • 2-3 cups mushrooms of choice I used shimeji, oyster and enoki mushrooms
  • 1 cup lotus root thinly sliced
  • 1/2 cup carrot julienned
  • 1/2 cup frozen shelled edamame

Instructions

  • Prepare your kombu dashi in advance by soaking a piece of kombu about the size of half of your palm in 2 cups of water overnight or for at least 3-4 hours.
  • Begin by combining kombu dashi, vegetable dashi, soy sauce, sugar and salt in your rice cooker or Instant Pot.
  • Next, prepare your rice by rinsing with your hands about 3-4 times in a bowl, draining the water in between rinses. If you're using an Instant Pot, let your rinsed rice soak in water for 15-20 minutes then drain well. This step gives the rice a chance to absorb moisture, it will not cook through all the way if you skip this step as the Instant Pot cooks it a little too quickly.
  • Add rinsed and drained rice to the rice cooker or Instant Pot along with all remaining ingredients. Give everything a gentle stir to, then cook as you normally would your rice. If using an Instant Pot, cook on high pressure for 2 minutes, let release naturally for 10 minutes, and manually release remaining pressure. Fluff rice immediately and transfer to an airtight container.

Notes

Secrets to Success

    • If you decide to make this kamameshi in an Instant Pot, please read the recipe directions carefully and make sure not to skip any steps! 
    • If using an Instant Pot, I highly recommend considering using a non-stick pot insert. Short-grain Japanese rice almost always burns at the bottom of the Instant Pot and causes the "burn" alarm to go off.
    • Kombu, or stock seaweed, can be found in the Asian section of most grocery stores and can be easily found at Asian grocery stores. As an alternative, you can opt to use a light vegetable broth.

Storage Tips

Store leftovers in an airtight container in the refrigerator and eat within 4-5 days. 
To freeze, let your kamameshi cool completely. Then, transfer to a freezer bag or freezer-safe container and freeze for up to 3-6 months.
