I like the smell of diesel, and other heavy oils. Are there any food ingredients, i.e. safe to eat, that have a taste similar to diesel. I think it would be an interesting experience to eat or drink something that had a taste that I associate with something that is most definitely not food. The question was prompted by a dispersible aspirin that has a chemical taste vaguely reminiscent of fuel oil. A beer or tea that tasted like diesel would be fascinating. I'd be interested in any other "not food" scents that have food safe sources, beyond the more familiar dichotomy transpiring from butyric acid. 
Retsina immediately springs to mind; it's a fortified wine stored in pitch-sealed barrels, and it develops a slightly kerosene-like aroma from that. Certain tequilas and mezcals also have a subtle diesel-like aroma.
