If you do choose charcoal grilling, we recommend additive-free lump charcoal, which is just charred wood. Conventional briquettes may contain wood scraps and sawdust as well as coal dust, sodium nitrate, borax and additives like paraffin or lighter fluid. As for lighter fluid, we recommend avoiding it altogether. Lighter fluid can release volatile organic compounds (VOCs) into the air, leave an unpleasant residue on food and pose a serious danger if used improperly.
