Vegan Fish Sauce (from GroupRecipes.com)
1.5 cup shredded dried seaweed
4 cups water
3 very large garlic cloves crushed but not peeled.
1.5 tbsp. black peppercorns
.5 cup dark Chinese soy sauce
Extra boiling water as needed*
Place the seaweed in a pot and add 4 cups of water.
Bring to a boil, then turn down the heat to keep it bubbling along.

Cook for 20 minutes.
Add the rest of the ingredients and enough water to make about 6 cups total in the pot.*at this point i added 2.5 cups water

Bring back to a boil, then boil fairly high for at least 1/2 hour.
At that point, begin to taste (just a little, though—it’s strong).
When the stock is reduced by about half, it will be almost too salty to eat, and that means it is ready.
Strain through fine mesh or a coffee filter and allow to cool.

I was a little unimpressed with the amount I got out of this recipe (a little more than half of a mason jar). I’d suggest doubling up. I haven’t used it yet but I plan on attempting some pad kra pao soon so I’ll update on how well this stuff works.
P.S. I need a wok.
