  1. Combine soy sauce, sherry, onion, olive oil, brown sugar, rosemary, garlic, and pepper in a bowl and mix well. Pierce flanks steak throughout using a large fork, flip, and repeat. Place steak in a plastic zip-top bag and pour in marinade to cover. Marinate in the refrigerator, 8 hours to overnight.
  2. Combine sour cream, green onions, horseradish, salt, and pepper in a bowl. Cover and refrigerate sauce until ready to use, up to 24 hours.
  3. Preheat an outdoor grill for high heat and lightly oil the grate.
  4. Drain steak and pour marinade into a small saucepan. Bring marinade to a boil over high heat and boil for 1 minute. Remove from heat. Season steak with pepper.
  5. Cook steak on the preheated grill to desired doneness, basting occasionally with marinade, about 5 minutes per side for medium doneness. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C).
  6. Transfer steak to a plate and let rest for 15 minutes. Cut across the grain into thin diagonal slices. Serve hot or at room temperature with horseradish sauce.
