When you cook fat and meat such as a BBQ polycyclic aromatic hydrocarbons(PAH) form and those compounds contain several benzene ring molecules. Part of the Maillard reaction process is the creation of PAHs. It's part of the process when cooking meat but not the only thing you taste. PAHs are used as a food additive "liquid smoke" to add a smokey, sweet flavour.
