One of the ways to select which 'flavor' of pellet to purchase is to group the wood pellets into three catagories: Soft, Medium, Hard.
Soft woods have loosely woven fibers, causing the pellet to burn cooler with more smoke. Alder and Apple wood are softer wood pellets.
Hard woods have tightly woven figers, causing the pellet to burn hot with very little smoke. Oak and Cherry wood are harder wood pellets.
Medium woods are somewhere in between the two.
Soft wood pellets are generally used for cooking poultry and fish - softer meats with a delicate flavor.
Hard wood pellets are generally used for firmer meats, steaks and beef roasts.
The medium wood pellets are an all purpose wood pellet - generally used by Owners who use one or two types of wood pellets for all their cooking. At the Big Belly Deli, we use Hickory, Pecan, or the last bag that broke.
Hickory is a medium wood perfect for grilling steaks, burgers or chicken quarters.
Mesquite is a medium wood more aromatic than hickory, and excellent for grilling burgers and steaks.
Pecan is a medium-hard wood, very versatile, and a good choice for long, slow cooking pork, beef, or poultry and grilling as well.
Apple & Alder pellets are soft woods, burn cooler and have more moisture in the wood than other pellets. These pellets are used for slow cooking fish and large poultry, such as turkey.
Onion & Garlic pellets are flavored pellets that have the associated flavor blended in with alder wood. Use sparingly, mixed in with other pellets to add extra flavor for certain foods.
Maple pellets have a lightly-smokey aroma, and are excellent for cold smoking cheeses, grilling vegetables and small poultry.
Cherry and Oak pellets are a hard woods and burn at hotter temperatures. Excellent for searing steaks and flash cooking fresh fish.
Grapevine is a very hard wood. Distinct aroma, versatile and can get very hot for searing and flash cooking.
