The Full Review

The WSM is the smoker that proves you don't need to spend thousands to produce world-class barbecue. I've produced competition-worthy brisket, ribs, and pulled pork on this $399 unit.

The secret is the water pan. It acts as a heat sink, moderating temperature swings and adding humidity to the cooking chamber. Fill it up, set your vents, and the WSM will hold 225°F for 8+ hours without intervention. In a Minnesota winter, I add a little more charcoal upfront, but the principle works the same.

Two cooking grates give you 481 square inches across two levels. That's two full packer briskets or six racks of ribs. For a smoker this compact, the capacity is impressive.

The "Minion Method" — filling the charcoal chamber with unlit briquettes and adding a small amount of lit charcoal on top — is the key technique. The lit coals slowly ignite the unlit ones, giving you 12+ hours of steady heat from a single load.
