How to Make the Ultimate Umami-Bomb Vegetarian Demi-Glace
1 tablespoon canola oil
1 medium onion, chopped
2 pounds carrots, sliced
4 quarter-size slices of peeled fresh ginger, lightly smashed
2 1/2 cups chicken stock or canned low-sodium broth
Salt and freshly ground white pepper
2 to 3 teaspoon fresh lemon juice
1 teaspoon honey
Dash of hot sauce (optional)
Fresh cilantro leaves, for garnish
Heat the oil in a large saucepan. Add the onion and cook over moderately low heat, stirring occasionally, until softened, about 5 minutes. Add the carrots and ginger and cook for 5 minutes, stirring occasionally. Add 2 cups of the stock, season with salt and pepper and bring to a boil. Cover and simmer over low heat until the carrots are tender, about 25 minutes.
Strain the cooking liquid into a heatproof bowl. Discard the ginger. In a blender, puree the vegetables with 1 cup of the cooking liquid until smooth. Stir the puree into the cooking liquid in the bowl and add the lemon juice, honey and remaining 1/2 cup of stock. Refrigerate until chilled or for up to 1 day. Season the soup with salt, pepper and hot sauce and serve garnished with cilantro leaves.
