Vegetarian Vietnamese Broth

I love vietnamese pho.

Put stock , soy sauce , garlic , and onion in a large stockpot and bring to a boil over medium heat.

Meanwhile , char ginger on all sides over an open gas flame or in a small skillet.

Add to the stock.

Add the cinnamon sticks , star anise , and bay leaves to the broth.

Reduce the heat to low.

Simmer , partially covered , for 20-25 minutes.

Remove solids with a slotted spoon or strain the broth through a fine-mesh sieve.

Adjust seasonings if necessary.

Return to pot and keep hot until ready to use in soup.
