The BBQ
River Cottage has a Komono oven. If you own one of these then read no further, however if you have yet to use a Komono oven there are a few key differences to a normal BBQ.
Use a high quality charcoal, there should be plenty in the shed to last you all week. If you run out please only use a good quality hardwood charcoal. It makes all the diference.
You can snuff out the charcoal when you have finished the cook, simply close both the top and bottom air vents. This will make the charcoal last a very long time.
Instead of me explaining I recommend you spend a little time on Youtube.
