Potato and green garlic chowder

Potato and green garlic chowder (Carlos Chavez / Los Angeles Times)

Total time: 1 hour, 15 minutes

Servings: 4 to 6

1/2 pound green garlic

1 1/2 pounds fingerling potatoes

2 tablespoons butter

1 onion, minced

2 cloves garlic, minced

4 cups chicken or vegetable broth

1 teaspoon salt, or to taste

1/2 to 3/4 teaspoon sherry vinegar

Black pepper

Good olive oil

Grated pecorino Romano

1. Trim the root ends of the green garlic and the very tips of the green leaves if they are dried out. Cut the green garlic crosswise in thin pieces. Slice the potatoes in half lengthwise and then into about half-inch pieces. Place them in a bowl of water to prevent coloring.

2. In a large saucepan, combine the butter and onion and cook over medium heat, stirring roughly until the butter melts and the onions turn soft and creamy, about 2 to 3 minutes. Add the garlic and the green garlic, reduce the heat to low, cover, and cook until the mixture is fragrant, about 5 minutes.

3. Add the potatoes and turn them in the garlic mixture. Add the broth and salt, increase the heat to medium and bring to a simmer. Loosely cover and cook at a quick simmer until the potatoes are soft enough to be smashed with a fork, about 20 minutes.

4. Coarsely purée the potatoes and garlic. This is most easily done with an immersion blender but can also be done in a food processor or blender if you're careful to pulse quickly. The mixture should be chunky, not a smooth purée.

5. Add one-half teaspoon sherry vinegarand a generous grinding of black pepper. Taste and add more salt, pepper or vinegar if necessary. Return to the pan and simmer another 5 minutes. This makes about 7 cups of soup.

6. Stir briskly just before serving. Ladle into warm serving bowls, drizzle with a thread of olive oil and sprinkle over 1 to 2 tablespoons grated pecorino Romano.
