1. In a shallow glass pyrex dish, combine the mirin, galangal and soy sauce. Place the well-pressed tofu into the marinade, flip to ensure a good coverage of marinade, and place in the refrigerator for a few hours.

To make the broth

1. Start by gently sauteing the ginger and garlic in a bit of oil in a medium-sized sauce pan for about 5 minutes over medium-low heat. Add in the stock, hollow lemongrass husks, vegan fish sauce, soy sauce and sugar. Stir well. Increase the heat to medium, and immediately dial it back to low once it starts to simmer.

To make the tofu

1. Heat a bit of oil in a large skillet over medium heat. Once the pan is hot, add the tofu and saute on each side for about 7 minutes, of until well-browned. Remove the lemongrass husks, then ladle the soup into bowls, top with tofu, and finish with whatever optional components you want.
