  2. Cool the Brine: Ensure the brine is cold before adding fish. If needed, place it in the refrigerator for 30 minutes.
    Submerge Fish: Place cleaned fish fillets or whole fish in the brine. Make sure the fish is fully submerged. You can use a plate or zip-top bag to keep the fish submerged if needed.

  3. Refrigerate & Brine: Cover the container and refrigerate for 8 to 12 hours. For thinner fillets, 6 hours may suffice; thicker cuts or whole fish benefit from the full 12 hours.
    Rinse & Dry: After brining, remove the fish and rinse under cold water. Pat dry with paper towels and place uncovered in the fridge for 1 to 2 hours to form a tacky surface (pellicle), which helps smoke adhere better.

  • Add flavor layers: Use maple syrup, bourbon, or fresh herbs in the brine to tailor flavors to your desired profile.
  • Batch friendly: This recipe can be doubled or halved easily depending on your needs.
