Nobu not Next Door. Downtown. Still worth the trip. But. Found gorgeous filet at Citarella couple blocks away on Broadway. Marinade 2 pieces cut crosswise in their Miso Asian Sauce or any of your favorite Miso Sauce. Refrigerate at least a few hours. Overnight to 48 hours is great. Remove from fridge and bring to room temperature. Wipe excess marinade from the cod with paper towels.
Cover and on medium cook until opaque. Maybe 5 minutes depending on thickness. Can add more sauce if desired.
Finally figuring out new stove. Yay.
