Mix the spices in a bowl and add some Iced Tea until you have a fluid mixture.
Insert the breasts with spiced Iced Tea and put aside for a half hour.
Light your fire for indirect cooking at 90° - 120°c / 200° - 250°F (depends on the time you want to go but the slower the better the result).
Add some wood chips to the fire.
Once the smoke is turning slightly blue you can start smoking the breasts. Aim for a internal temp of 72°C / 160°F. It took me about 1h15m. I basted the breasts with the remaining liquid during the last 5-10 minutes. It's not necessary but it adds a bit of flavour to the outside.
Have a nice meal.
