Ingredients

2 tablespoons unsalted butter

2 scallions, thinly sliced, white and green parts separated

Large pinch saffron

4 cups low-sodium chicken broth, warmed

2 russet potatoes, cut into 1/2-inch pieces Kosher salt and black pepper

1 1/2 pound piece boneless, skinless cod

2 cups frozen corn, thawed

1 cup half-and-half

Preparation

Melt the butter in a large pot over medium-high heat. Add the scallion whites and saffron. Cook, stirring, until softened, 1 to 2 minutes. Add the broth, potatoes, 1 teaspoon salt, and 1/4 teaspoon pepper. Cover and bring to a boil. Reduce heat and simmer until the potatoes are tender, 8 to 10 minutes. Add the cod, corn, and half-and-half. Cover and bring to a simmer. (The fish will cook through as the soup returns to a simmer.) Serve topped with the scallion greens.
