Long Burn Charcoal Briquettes

Uniformity Enables Prediction

Every briquette is the same size and density, which means a known quantity produces a known amount of heat for a known time.

That predictability is what makes competition cooks use briquettes despite lumpwood burning hotter, since a repeatable result matters more than peak temperature.

Lumpwood varies bag to bag and piece to piece, which is fine for grilling and is a genuine complication over a twelve hour cook.

Binders And What Is In Them

Briquettes are charcoal dust compressed with a binder, typically starch, and some brands add coal, borax, sawdust or other fillers.

Plain briquettes with only charcoal and a starch binder burn cleanly, and cheaper ones with additives produce more ash and a different smell.

Reading the composition where it is stated is worth doing, and brands that do not state it are making a choice about disclosure.

Ash Production Is Higher

Briquettes produce considerably more ash than lumpwood, which accumulates during a long cook and restricts airflow at the bottom vent.

That is the practical cost of the binder and filler content, and it is why long cooks on briquettes need ash management partway through.

Ash pans, raised grates and simply shaking a kettle to drop ash through all address it, and ignoring it produces a fire that slowly chokes.

The Snake And Minion Methods

Arranging briquettes in a line or a ring and lighting one end produces a fire that burns progressively along it for many hours.

That is only possible because briquettes are uniform, since irregular lumpwood does not form a predictable line.

A snake with wood chunks placed along it produces smoke progressively as the burn reaches each one, which distributes flavour across a cook.

Instant Light Products

Briquettes pre-soaked with accelerant light without a chimney and taint food with the same petrochemical flavour as lighter fluid.

They exist for convenience and are entirely unnecessary given that a chimney starter lights plain briquettes in fifteen minutes.

Anybody who has used them and disliked the result should try plain briquettes before concluding charcoal cooking is not for them.

Lighting time is longer than lumpwood, since the density that gives briquettes their steady burn also means they take longer to light through in a chimney. Twenty minutes rather than fifteen is a reasonable expectation, and rushing a chimney produces partly lit fuel that then burns unevenly. Waiting for grey ash across the top of the chimney is the signal rather than the clock.

Bag weight is worth noting before buying, since a full sack of briquettes is heavy enough that carrying one from a car to a garden is a genuine effort for some people, and decanting into a bin at purchase avoids repeating it.

Mixing briquettes with lumpwood gives steady heat from the briquettes and a hotter searing zone from the lumpwood, which some cooks use deliberately.

Shape varies between pillow and hexagonal briquettes, and the flatter shapes stack more closely in a snake where rounded ones leave gaps that break the burn.

The Verdict

The right fuel for long predictable cooks, where uniformity enables techniques lumpwood cannot support.

Ash production is high, fillers vary between brands, and instant light versions taint food.

Briquettes make the snake method possible. Uniform fuel is what lets a fire burn predictably for hours.
