The snake method for BBQ — how does it work and when do you use it?
The snake method, also called the C-method, arranges briquettes in an open arc around the edge of a kettle barbecue. You light one end and the burning zone gradually moves along. This can provide sustained indirect heat with less frequent refuelling. Burn time and temperature are not fixed: fuel, layout, airflow and weather all matter. The method still needs supervision.
What is the snake method and how do you build it?
The unlit briquettes touch one another so that the glowing zone can ignite the next pieces. Keep the arc open and prevent its beginning and end from igniting each other. Build it on the charcoal grate, not the cooking grate.
Briquettes and layout
A common layout is two rows wide and two layers high, often written as 2×2. Maintain good contact without blocking airflow. A gap of around 15–20 cm between the beginning and end can be a practical starting point, but the required distance depends on your barbecue and fuel.
A third layer, 2×3, adds fuel and can also increase heat output. It is not an automatic solution for every longer cook. Test how your kettle responds first. Regularly shaped briquettes make the layout easier to manage; this guide uses them. Saying the method ‘never works with lump charcoal’ is too absolute. Irregular pieces require extra attention to contact and combustion. Read more about briquettes versus lump charcoal.
Water pan and smoking wood
Place a heat-resistant drip or water pan securely in the centre, clear of the snake. Food sits on the cooking grate above the pan, not above the burning briquettes. Water can help moderate temperature changes; check the level and refill carefully with heat-resistant gloves. A pan boiling dry changes how the setup behaves. Read more about using a water pan in a barbecue.
Place a modest amount of suitable smoking wood near the beginning of the snake, such as a few small chunks. Smoke output depends on quantity, placement and combustion. There is no fixed two-to-three-hour period after which meat can no longer take on smoke flavour. More wood is not automatically better.
What are the advantages and how long does it burn?
The layout makes the path of the burning zone easy to see. Because the full fuel supply is not burning strongly at once, suitable airflow control can make a kettle useful for low & slow cooking. You may need to add fuel less often than with a small, fully lit pile of charcoal.
A fixed promise of four, six or eight hours is not appropriate. Briquette brand and size, snake length and cross-section, vent settings, outdoor temperature, wind and use of a water pan affect the result. A longer, well-functioning setup can also run for more than eight hours. Plan spare fuel and monitor progress; ‘less frequent refuelling’ does not mean ‘no supervision’.
When does the snake method need extra attention?
| Situation | What matters? | Practical approach |
|---|---|---|
| Long cook | Fuel may run out; there is no universal eight-hour limit. | Monitor temperature and fuel use. Plan safe refuelling or another suitable setup. |
| Large or thick cut | You need sufficient indirect cooking space. Five kilograms is not a fixed limit. | Check clearance above the snake, barbecue capacity and the recipe. |
| Wind or cold | Heat loss and airflow may change. | Choose a safe, sheltered outdoor position before lighting. Never enclose the barbecue to block wind. |
| High direct heat required | The snake is for controlled indirect cooking, not a large direct grilling area. | Use a suitable fuel arrangement and follow the appliance manual. |
| The burning zone stops or spreads too quickly | Poor contact, insufficient airflow or a bridge between parts of the snake may contribute. | Check contact, vents and ash build-up. Do not blindly keep adding more lit briquettes. |
Too few or insufficiently lit starter briquettes can make ignition difficult, but they are not the only possible cause. Too many starters can make the barbecue too hot.
Snake method versus minion method
Both methods use a limited amount of lit fuel to ignite a larger supply gradually. The fuel layout differs; neither guarantees a temperature or burn time without suitable airflow control.
| Feature | Snake method | Minion method |
|---|---|---|
| Layout | Open arc of touching briquettes around the edge. | A fuel bed with a limited amount of lit briquettes; placement varies with the setup. |
| Progression | The burning zone mainly follows the arc. | Lit fuel ignites neighbouring fuel in the bed. |
| Use | Especially associated with kettle barbecues. | Used in suitable water smokers and kettles, among other setups. |
| Burn time | Depends on fuel supply, layout, appliance, airflow and weather. | Also depends on fuel supply, layout, appliance, airflow and weather. |
| Supervision | Keep checking temperature and progress. | Keep checking temperature and progress. |
A snake can work for ribs, pulled pork and brisket when capacity, fuel and recipe fit the setup. A longer cook does not automatically require buying a different appliance. Read more about managing fuel during a barbecue session.
The snake method step by step
1. Check and build the setup
Start with a cold, clean barbecue on a stable, non-combustible outdoor surface. Keep vents clear of ash. Build the touching, open arc on the charcoal grate and make sure its beginning and end cannot meet. Use fuel suited to your appliance and cooking method.
2. Add the water pan and wood
Position the pan securely in the centre, next to the snake. Add warm water carefully if using water. Place a small amount of smoking wood near the first part of the snake and keep the setup accessible for checks.
3. Light one end
Light the starter briquettes thoroughly in a suitable chimney starter and use heat-resistant gloves and utensils to place them against the beginning of the snake. For a typical 57 cm kettle, Weber gives around 8–10 starter briquettes as an example. This is not a minimum for every barbecue or briquette. Never use petrol or methylated spirits to boost the fire.
4. Stabilise the temperature
Close the lid and control airflow according to the appliance manual. Measure the air temperature near the food at cooking-grate level, not directly over glowing coals. A lid thermometer can give a different reading. Many low & slow cooks use a working range around 110–135 °C; choose the temperature specified in your recipe. A fixed quarter-open vent or fixed warm-up time will not suit every kettle. Make small vent adjustments and give the barbecue time to respond.
5. Cook indirectly and keep checking
Place food above the pan, clear of direct heat from the snake. Monitor cooking-grate temperature, the burning zone and the water level where relevant. Assess doneness and food safety separately: barbecue temperature is not internal food temperature or a guarantee that food is ready. If temperature falls, first check fuel, contact and airflow.
Also read about temperature, time and texture when assessing doneness and managing the BBQ stall.
Working safely during a long barbecue session
Use a charcoal barbecue only outdoors in a well-ventilated position. Never use it inside a house, garage or tent, even with a door open. Keep it away from combustible materials and prevent smoke and carbon monoxide from entering buildings. Do not move a burning or hot barbecue.
Do not leave it unattended or go to sleep while it is burning. A thermometer alarm does not replace supervision. Keep children and pets away and protect yourself from hot coals, steam and hot water. After cooking, follow the manufacturer's shutdown instructions and let the barbecue and coals cool completely outdoors before clearing up.
Low, controlled heat and a suitable rub
The setup helps you manage heat; a rub adds flavour. Choose a blend to match the dish.
