I certainly don't have this done pat by any means, hell, only my 3rd go - over past 18 months
So I filleted the Tommies and butterflied the Gar and put them in a brine of 1lt water, 1/4 cup salt and 1/4 cup of brown sugar and in the fridge for 24 hours+.
Got my 'deluxe' Mojiko smoker ready but only had Samba Poultry/Pork chips, so they had to do.
Smoke vent was only just open a tad and smoking well.
Thought maybe 45 minutes but this 30 minutes in, so them off.
Look over done to me compared to other that have a darkish tan, but they tasted ok - a little dry maybe.
