Low and slow

Low and slow describes cooking at a relatively low temperature, generally somewhere between 225 and 275 degrees Fahrenheit, for an extended stretch of time, often many hours. It is the method behind brisket, pork shoulder, ribs and other cuts loaded with tough connective tissue and collagen that will not soften at high heat no matter how long it sits, but breaks down into tender, gelatinous texture when held at a gentle temperature for long enough.

The long timeline also gives smoke a chance to penetrate and build flavor, and it gives a well-seasoned surface time to form bark. This is different from grilling a steak or burger, where the goal is a fast sear, because low and slow cuts are usually tougher and fattier, and rushing them with high heat just dries them out on the outside before the inside has softened.

A steady low temperature depends on good airflow control and enough fuel to last the cook, whether that is a bed of charcoal, an auto-feeding pellet hopper or a gas burner turned down low. A common mistake is chasing every small temperature swing with drastic vent or burner changes, which makes the cook harder to manage than simply making small adjustments and giving the system time to respond.
