Step 1

In a small skillet over medium heat, combine the water, dulse flakes, shiitake mushrooms, garlic, salt, and pepper. Don’t add the soy sauce and miso just yet.

Step 2

Bring the mixture to a boil. Reduce the heat and simmer for 25 minutes, or until the liquid is reduced by about half.

Step 3

Strain the mixture. We used a funnel with a built-in strainer, but you can also use a sieve. Let cool.

Step 4

Add two tablespoons of soy sauce and one teaspoon of miso, then whisk well. Taste and add more soy sauce, miso, or salt as necessary.

Step 5

To serve, garnish the fish sauce with chili pepper flakes, sliced garlic, and/or sliced jalapeno peppers.
