A great fire should not feel rushed. It should begin with dry timber, a deliberate stack and enough time for flame to turn into the glowing hardwood coals that give meat its deep crust, vegetables their sweetness and the whole cook its unmistakable woodfire character. Knowing how to light hardwood coals is the difference between cooking over a dirty, uneven blaze and running a proper fire with heat you can read, move and control.
For a parrilla cook, the goal is not a roaring bonfire under the grill. It is a reserve of clean-burning embers that can be raked beneath the food as needed. Get that foundation right and the rest of the afternoon – steak, lamb, wine, great company and good times – falls into place.
Start with the right hardwood
Hardwood coals begin with good fuel. Use dry, untreated hardwood that has been properly seasoned, ideally for at least 12 months. Red gum, ironbark, box, stringybark and other dense Australian hardwoods are all capable of producing long-lasting coals, although every species burns a little differently. Dense timber generally delivers a longer, more powerful coal bed; lighter woods catch quickly and are useful for getting the fire established.
Avoid painted, treated, glued or reclaimed building timber. It can release unpleasant and unsafe fumes, and it has no place near food. Green wood is equally frustrating. Its moisture steals heat from the fire, creates excessive smoke and leaves you waiting for coals that never quite arrive.
Split pieces are better than oversized logs when starting out. You need exposed edges and enough airflow for the fire to take hold. Once the base is burning strongly, add larger splits to build your coal supply.
How to light hardwood coals from scratch
Choose a clear fire area and begin with a small, purposeful build. In a fire basket or on one side of a parrilla firebox, lay two or three small splits with space between them. Add a layer of dry kindling over the top, then place one or two natural firelighters where the flame can reach the kindling easily.
Light the firelighter and let the first small flames do their work. Resist the urge to pile on heavy logs immediately. A fire needs oxygen as much as fuel, and smothering a young flame is one of the quickest ways to make thick, bitter smoke.
When the kindling has formed a lively flame, add a couple of medium hardwood splits in a loose criss-cross pattern. This creates channels for air to move through the stack. Leave the fire to burn with the vents open, if your grill has them, until the new timber is well alight. The flame should be active and bright, not lazy and smoky.
After 20 to 40 minutes, depending on the timber, your first logs will begin to collapse into embers. At this stage, use a fire poker or rake to bring the glowing material together. Add another split or two to the top or side of the fire, rather than laying them directly across the coal bed. You are now building a bank of coals, not merely keeping flames alive.
A handmade fire basket earns its keep here. It keeps the wood contained, lifts it clear of ash, encourages airflow and gives you a dedicated place to make coals while the cooking zone stays organised. On a gaucho-style grill, that separation lets you feed hot embers beneath the grate without disrupting the food above.
Wait for embers, not flames
The most common mistake in woodfire cooking is putting food over the fire too early. Tall flame looks impressive, but flames are inconsistent and can leave soot on food. Hardwood coals are ready when they are glowing through a coat of pale grey ash, with little or no heavy smoke coming from the fuel.
Do not treat the ash colour as the only signal. A coal can look grey on the surface yet lack the heat for a hard sear, particularly if it has been sitting too long. Use your tools and pay attention to the way the ember bed behaves. Fresh coals glow orange-red when raked open and throw a clean, dry heat. Older coals look duller, hold steadier heat and are ideal for gentler cooking.
For steaks, chops and quick-cooking cuts, rake a concentrated layer of fresh hardwood coals beneath the hottest part of the grill. For chicken, thicker fish, vegetables or slow-cooking beef ribs, spread the embers further apart and create a cooler section nearby. A parrilla’s adjustable grill height adds another level of control: lower for intense radiant heat, higher when the fire is doing more than the food needs.
Build a fire with more than one temperature
The best live-fire cooks do not chase one perfect temperature. They create zones. Keep a live fire burning to one side, establish a high-heat coal bed in the centre and leave a lower-heat edge for resting, finishing or holding food. This gives you options when fat begins to render, when a steak needs a final kiss of heat, or when a beautiful crust is ready but the centre needs more time.
Move coals with intent. A small mound burns hotter than a thin spread, while a broad, shallow layer is more forgiving. If the heat under one section of the grill drops, rake in a shovel of fresh embers from the fire. If it is running too hard, spread the coals, raise the grill or move the food to a quieter zone.
This is where fire cooking becomes less about guesswork and more about rhythm. You are feeding the fire, reading the coal bed and responding to what is happening in front of you. The tools matter too. Long-handled fire tools and proper heat-resistant gloves allow you to work close enough to control the embers without taking foolish risks.
Keep the smoke clean
A little smoke is part of the appeal. Acrid, rolling white smoke is not. Clean smoke usually means the wood is dry, the fire has enough oxygen and the flames are burning the gases released by the timber rather than choking on them.
If your fire is smoking heavily, do not cover it with more wood. First, check whether ash has built up beneath the fire and restricted airflow. Then separate tightly packed logs with a poker and add a smaller dry split if the fire needs help. A brief puff of smoke when adding a log is normal; a persistent cloud that stings your eyes is a sign something needs adjusting.
Never use petrol, methylated spirits or other accelerants to hurry the process. Apart from the obvious danger, they can taint the cooking area and turn a relaxed fire session into a bad story. Natural firelighters, dry kindling and patience deliver a far better result.
A simple timing guide for a weekend cook
If guests are arriving at lunch, light the fire around 45 to 60 minutes before you plan to cook. That may feel early, but hardwood rewards patience. You want enough coals ready before the first steak hits the grate, plus a live fire still producing fresh embers for the second round.
Start with smaller splits, then introduce larger pieces once the base is established. Keep one or two dry splits nearby so you are not scrambling for fuel with a grill full of food. If you are cooking a long session, maintain the side fire throughout rather than trying to revive a fading coal bed later.
Smokin’ Gauchos builds its fire cooking gear around this exact ritual: make the fire properly, manage it with confidence, then let the food and the gathering take centre stage.
Hardwood coals are not a shortcut, and that is their strength. Take the time to build a deep ember bed, give yourself hot and quiet zones, and cook with your hands close to the fire. The result is more than dinner – it is the kind of afternoon people remember long after the last coal has gone dark.
