Extra time from smoking a part-frozen turkey. Or less time due to a higher heat source.

What Types Of Meat Is There In A Turkey?

There are 2 types of meat in a turkey.

Dark meat in the thigh and white in the breast meat.

The darker meat is located nearer the bones. It has a gamey taste and more fat.

White meat is lighter-tasting, dense, and tender. But can be prone to going dry.

What Does Smoking Do For Turkey Meat? 

This temperature is first a balance in achieving the perfect holiday meal.

With that delicious smoky flavor filling the room minutes before carving!

Indirect heat with simple rub ingredients for a delicious flavor.


This temperature is hot enough to penetrate the meat and cook it thoroughly. So there is no nasty surprise when you start carving!

Adding Flavor 

Smoking is our cooking method but it also adds extra flavor. 

The smoke flavor at 275-300 degrees has enough time to penetrate the skin. This helps create a depth of flavor you will never forget!

The type of wood you use will make a difference in flavor too. I use fruit woods in my meat smoker for turkey.

Chemical Reactions For Tender Meat & Crispy Skin

The smoke and temperature will also create some tasty chemical reactions!

The heat will partly evaporate the moisture within the proteins. The juices will then baste which keeps tenderizes and forms flavorful meat.

The smoke will also bind and render the fat in the skin and connective tissue.

Are you using brown sugar in a spice rub? You should!

The Millard reaction will help form a picture-perfect crust on the skin!
