Prepare the smoker for smoking. Bring the fish into the smoker, place one temperature probe in the middle of a piece of mackerel and let the temperature very gradually rise. Do this by adjusting the air flow and/or by adding some apple or hickory wood coals low in the smoker
Bast the fish in the last 3 hours each hour with maple syrup or honey
Ensure the end-temperature of between 55-60 C is not exceeded and maintained for at the least 40 min to ensure the fish pieces are cooked in the right manner
After 3.5 -4 h take out the fish pieces from the smoker and let them cool down, away from insects
Then place in the fridge to further dry and cool for 4 h
Finally remove the remaining bones and wrap the mackerel halves or vacuum seal them. The latter will enable a longer storage time. Store in the fridge for over a week or in the freezer for months.
