3 tablespoons unsalted butter
1/2 Cup Pino Gris
1/4 C Dave’s soup base
4 large leeks, white and light green parts only, roughly chopped (about 5 cups)
3 cloves garlic, peeled and smashed
2 pounds Yukon Gold potatoes, peeled and roughly chopped into 1/2-inch pieces
7 cups low sodium chicken or vegetable broth
2 bay leaves
3 sprigs fresh thyme
1 teaspoon salt
1/4 teaspoon ground black pepper
1 cup heavy cream
3 Ripe Kohlrabi (about the size of a baseball) cut the same size as the potatoes
1/2 red onion diced
Chives, finely chopped, for serving
- Melt the butter over medium heat in a large soup pot. Add the leeks, onion, garlic, Pinot Gris, and cook, stirring regularly, until soft and wilted, about 10 minutes. Adjust the heat as necessary so as not to brown.
- Add the potatoes, Kohlrabi, broth, bay leaves, Dave’s soup base, thyme, salt and pepper to pot and bring to a boil. Cover and turn the heat down to low. Simmer for 15 minutes, or until the potatoes are very soft.
- Fish out the thyme sprig and bay leaves, then purée the soup with a hand-held immersion blender until smooth. (Alternatively, use a standard blender to purée the soup in batches; see note.) Add the heavy cream and bring to a simmer. Taste and adjust seasoning with salt and pepper. If soup is too thin, simmer until thickened. If it’s too thick, add water or stock to thin it out. Garnish with fresh herbs if desired.
- If using a standard blender to purée the soup: be sure not to fill the jar more than halfway; leave the hole in the lid open and cover loosely with a dishtowel to allow the heat to escape; and pour blended soup into a clean pot.
Dave’s soup base consist of spent brewer’s grains dehydrated, and ground with salt, pepper, and dried basil.
