To make this recipe, start in the produce department and pick up an onion, white mushrooms, cremini mushrooms, lemon, fresh dill, and flat leaf parsley. From the dairy aisle, grab some butter, milk, and sour cream. Then, round out your visit with vegetable or chicken broth, soy sauce, flour, paprika, salt, and pepper. “We are using regular paprika for this soup, but you can substitute that with smoked paprika if you like a smoky flavor. That variety tends to be very strong, so you will only need about 1 teaspoon,” Hahn says.
