Lump charcoal, which is naturally irregular in shape and size, is the purest form available, made without any additives. It lights quickly, cooks hotter and leaves less ash behind than briquettes, which is helpful if you’re cooking on a grill that doesn’t have a lot of space for ash to collect. It also gives your food that delicious smoky flavour often associated with charcoal BBQs.
Briquettes are made from the bits of charcoal leftover when lumps are created. Additives are used to bind everything together and create uniform pieces of charcoal. Briquettes don’t burn as hot as lumps, but they do last much longer.
