• Before You Start: Please note that this recipe has a curing time of 2 days.

To Cut the Fillets (optional)

• If you're using pre-cut fillets, skip to To Salt the Salmon. To cut fillets from a side of salmon, follow my detailed instructions with photos in How to Cut Salmon into Japanese-Style Fillets.

  Brief overview: Place a side of salmon skin side down with the tail end to your left. (The tail end is narrow and the head end is wider). Cut off the tail‘s narrowest part, which is too small for Japanese-style fillets. Then, tilt your knife back 30 degrees and slice the salmon diagonally toward the tail end about 1 inch (2.5 cm) thick.
  
• This 1.3 lb (600 g) side of sockeye salmon yielded 8 Japanese-style fillets and 3 additional odd-sized pieces.
  

To Salt the Salmon

• Sprinkle 1–2 Tbsp sake over 1.3 lb skin-on Japanese-style salmon fillets. Turn to coat all sides. Let sit for 10 minutes.
  
• Pat the salmon dry with a paper towel.
  
• Sprinkle some of the salt on the skin. Sprinkle the remaining salt on both sides of the fillets.

  Nami's Tip: I use 5% of the salmon's weight in salt. In Japan, the salt concentration ranges from 3–8% or more; see my blog post for more information.
  
• Press any leftover salt onto the skin.
  

To Pack and Cure

• Line the bottom of an airtight container with a paper towel to absorb moisture. Place a few salted fillets in a single layer in the container, then place another paper towel on top.

  Nami's Tip: The salt will draw out the moisture from the salmon.
  
• Repeat for the second and third layers.
  
• Lay a final sheet of paper towel on top. Cover and refrigerate for 2 days.
  

To Pat Dry

• Open the container after 2 days and discard the wet paper towels. The fillets should be darker and firmer.
  
• Gently pat the fillets dry with a clean paper towel. The salted salmon fillets are now ready to use. To cook them now, jump to the “To Broil“ section. To freeze the fillets to use later, see the next step.
  

To Freeze for Later (optional)

• Wrap the cured salmon fillets individually or in pairs to freeze and cook later. To wrap two fillets together in the same sheet of plastic wrap, see the next step.

  Nami's Tip: I usually wrap two fillets together, as I often need two for bento boxes or four for a family meal.
  
• To wrap two fillets together, fold one corner over one fillet, covering it completely. Place the second fillet next to it, separated by the plastic layer. Roll both tightly in the plastic wrap.

  Nami's Tip: Separating the fillets with a layer of plastic wrap keeps them from fusing together when frozen. This is helpful when you need to take out just one frozen fillet.
  
• Wrap the rest of the fillets. Put them in a freezer bag and store in the freezer for up to 1 month.
  

To Defrost the Frozen Fillets

• The night before cooking the salmon, place the frozen wrapped fillets in the refrigerator overnight to defrost completely. Let the salmon sit on the counter for 15–20 minutes to warm to room temperature.

  When you're ready to cook, gather all the ingredients.
  

To Broil (recommended)

• Place the oven rack in the center position, about 9 inches (23 cm) away from the top heating element. Preheat the oven broiler on High (550ºF/288ºC) for 5 minutes.

  Line a baking sheet with foil and grease it with a thin coat of (spray) cooking oil. Place the salmon on the foil, skin side up (for crispy skin).

  Nami's Tip: I use foil for easy clean up. When broiling, you don‘t control the temperature in the oven. Instead, you control the distance between the broiler and the surface of the food. It‘s similar to using hotter and cooler zones on your grill.
  
• Broil the salmon for 8–10 minutes, until well done—it should be flaky and more dry. No need to flip it.

  Nami's Tip: The cooking time varies depending on the thickness of the fish and the distance between the broiler and the food.
  

To Bake (optional)

• If you don't have a broiler, preheat the oven to 425°F (218ºC) with the rack placed in the middle position. Bake the salmon on a baking sheet lined with parchment paper for 10–12 minutes, until well done (more dry and flaky).

To Grill (optional)

• If you prefer, cook the fillets on a wire fish grill on medium heat over a stovetop or direct fire. Cook about 5 minutes on each side, until well done (more dry and flaky).
  

To Serve

• Peel 2 inches daikon radish. Grate and gently squeeze out most of the liquid, keeping it moist.

  Nami's Tip: I use a ceramic grater.
  

To Serve

• Serve the broiled salmon with grated daikon on the side.

  Nami's Tip: I also served Tamagoyaki (Japanese Sweet Rolled Omelet) and Spinach Salad with Sesame Dressing in this meal.
  

To Store

• Store in an airtight container in the refrigerator for up to 3 days and in the freezer for up to 2 weeks. Do not refreeze previously frozen fish.
