There are things that need a special piece of equipment.
Grilling and smoking are two of these things.
Although in some cases you can use a grill to smoke, when it is large enough for 2-zone setup, most of the time you can not grill on a smoker.
What is grilling?
Grilling is done over a hot bed of coals. Directly or indirectly.
Meat is cooked fast to sear it and then can be moved to a cooler spot to finish or stay above the hot coals in case of a thin piece of meat.
Examples of grilling are: Hamburgers, hot dogs, chicken.
What is smoking?
Smoking meat is done on a low temperature of around 225 to 250 degrees and can take many hours depending on the meat you are smoking.
Examples of smoking are: Boston buts, brisket, whole chicken.
Technically this is not a smoker. Its is my grill that I use for smoking. The indirect set-up allows me to keep the temperature low.
Smoking on a grill?
You can use a grill for smoking when it is large enough as you can see on the picture above.
This is a very short and compressed explanation of the difference between grilling and smoking.
I will write several more articles on how to grilll and smoke meat.
