I recently bought a fire pit which can be used as a bbq, but I'm not sure if you are supposed to/can use logs on it when you are using it as a bbq and cooking food, or if you have to use charcoal?
Sorry for my ignorance, but I've only used small bbqs before when camping, and I know usually you put logs on a fire pit, so I'm confused!
You can cook over logs on it but you need to keep the food/pots to the outside edge of the fire where there aren't any flames, just embers, as flames will cook food too fast and blacken it. It's just like using a bbq really, you need the flames to die down and just use the heat from the red embers.
Only use hardwoods, though. Other resinous woods can give off an acrid taste to the food grilling the vicinity. No pine other needle woods. Oak is fine, Birch is not, due to resin. Beech is. Most petrol stations sell sacks of hardwood logs for the fire. Use them and you'd be okay.
