Sardine Miso Ball Soup
From: Saveur
SERVES 4
FOR THE SARDINE BALLS:
2 tbsp. sake
1 tbsp. white miso
2 tsp. potato starch
8 fresh sardines, cleaned and filleted, skins removed, or 2 (4-oz.) cans boneless skinless sardine filets packed in oil, drained
1 (2”) piece ginger, peeled and grated
1 egg, beaten
Kosher salt, to taste
For the soup:
1 (4”-square) piece kombu
1 oz. bonito flakes
3 oz. medium-firm tofu, cut into ¼” pieces
2 tbsp. mirin
1 tbsp. light soy sauce
Kosher salt, to taste
5 scallions, white and light green parts, thinly sliced
1 bunch mitsuba, thinly sliced (optional)
Make the sardine balls: Purée ingredients in a food processor until smooth; transfer to a bowl and chill until ready to use.
Make the soup: Place kombu and 6 cups water in a 4-qt. saucepan; let sit until soft, about 15 minutes, then bring to a boil. Remove from heat, and stir in bonito; let sit 5 minutes, then strain broth and return to pan. Bring broth to a simmer over medium heat. Using a 1-oz. scoop or 2 spoons dipped in water, drop sardine balls into broth. Cook, without stirring, until balls float, 2–3 minutes. Stir in tofu, mirin, soy sauce, and salt and ladle soup into bowls; garnish with scallions and, if using, mitsuba.
