Best way: use a food thermometer!
The internal temperature should measure 125 to 130 degrees Fahrenheit in the center for medium cooked salmon. Make sure you insert the probe into the thickest spot.
Beside above, how do you tell if smoked salmon is done?
Gradually increase the temperature inside the smoker over the course of the day so that during the last hour or so it hovers between 150° and 160°F. Smoke the salmon until it reaches an internal temperature of 145°F in its thickest part, which will take eight to ten hours.
Thereof, how long do you smoke salmon at 180 degrees? Smoke: Get the temperature of your wood or pellet smoker up to 180°F, with a water tray in the smoker for moisture and to balance out the temperature, then place the salmon skin side down on the grates and smoke for 4 to 5 hours, until the internal temperature reaches 135°F to 140°F.
Beside this, is salmon safe at 120 degrees?
When wild salmon is cooked to just 120 degrees, the muscle fibers retain more moisture. Farmed salmon contains more fat than wild salmon, so it can be cooked a few degrees longer without drying out.
