It’s time to go Au Natural.

Au Natural is a 100% natural compressed briquette charcoal. We make it without binders, so there are no nasty chemicals to spoil the flavour of your cooking. It’s compressed from waste saw dust and wood chips at high pressures to create moulded hexagonal tubes that are consistently sized and shaped, meaning they’re easy to handle and burn cleanly. These tubes have a central hole to aid air flow, which ensures they burn evenly across your barbecue, with no hot or cold spots to manage.

With a cooking time of over 3 hours, Au Natural is dependable and long-lasting. It’s best used in combination with our Chilla-Grilla lumpwood charcoal as a lighting aid. Au Natural is used to power professional grills across the country, but it’s also popular among adventurous home barbecuers.

If you’re looking to keep your BBQ clean and full of flavour, Au Natural is perfect for the purists.

Please note all cooking times are approximate and depend on a range of factors, including quantity of charcoal and type of barbecue used, lighting method and weather conditions.

    Great service.
    Best charcoal that I have ever used. Last for so long and generates a superior heat inside the BBQ.
    I even use the remainder to start my log burner after cooking on the BBQ.

    Absolutely brilliant. It does take a while for the coal to go completely grey. But once its ready you can keep your BBQ going for 3 hours.

    Amazing fuel. I use Cobb ovens and this fuel can last up to 5 hours, depending on what I’m cooking. A small basket of RCB10 can cook 2 courses. This fuel is cost effective because it can be stifled or doused when you’ve finished cooking to save any remnants that can be used again. RCB10 is my fuel of choice to cook in my Cobb ovens. RCB10 can give temperatures in the Cobb dome of well over 200°c which makes it an excellent fuel for roasting meats and vegetables.

    So ya wanna long burn, well you’ve come to the right place cooked a Brisket last weekend, started proceedings with some Chilla Grilla then added Au Natural 5.5hrs later & the meats done so used as a patio heater. These two together are your answer to low & slow it’s the truth.

    This is my first box and only tried a couple of sticks to test burning time and is very long.
    Not yet tried a long cook as I need more time familiarize myself with it.

    This is perfect for long slow cooking in weber or egg style bbq. So much nicer than other chemical briquettes with its smoky flavour and all natural. Took a couple of goes to figure out best way to use but will be our regular option alongside big k lumpwood which is just as good and the applewood briquettes for variety.
    Service and delivery from BigK was great too.

    I use this fuel in my Cobb oven. It’s a super clean fuel with a long burn.
    RCB10 provides excellent reliability and consistent heat and burns for approximately 1 hour per centimetre in the Cobb Premier and around 40mins per centimetre in the Cobb Premier AIR model.
    This fuel is great for snaking fuel for longer cooks (low and slow) as there’s no nasty, smelly accelerants tainting the food.
    RCB10 can be extinguished either by dousing in water or stifling the oxygen, ready to use another time.
    One basket of 7x 5cms pieces of RCB10 has the potential to cook 3 courses in the Cobb Premier.

    In my opinion, this is one of the best fuels to use in the Cobb oven models. It’s cost effective.
    I use RCB10 pretty much daily as I Cobb our dinners every day.

    Look up I Love My Cobb group on Facebook for examples.

There are two methods to lighting Au Natural:

Method 1: Using Chilla Grilla

Create a base of charcoal using Chilla-Grilla lumpwood charcoal, add 3-4 Big K firelighters and light. Once the firelighters are burning, cover with additional charcoal to make a pyramid. This allows the flames to rise up from the bottom, heating the coals quickly and evenly.

After approximately 30 minutes, spread the coals out and add Au Natural on top. Wait for a further 10-15 minutes and you're ready to start cooking.

Method 2: Without Chilla Grilla

Create a base of Au Natural briquettes, add 5+ Big K Firelighters and light. Once the firelighters are burning, cover with additional charcoal to make a pyramid. This allows the flames to rise up from the bottom, heating the coals quickly and evenly.

After approximately 30 minutes, spread the briquettes out. Then, simply wait another 10 minutes and you're ready to start cooking.

Free next day delivery on orders over £30 (inc. VAT). For order values less than £30 a delivery charge of £8 applies. Exclusions apply outside of mainland UK, click here for more details on surcharges. Deliveries are made by Parcelforce or DPD.
