When you are working in a lab, try to refrain from tasting things that have not been labeled. I suppose it could have been poison, but I was lucky. That full body shiver I had almost threw my back out. Ew..
It has been confirmed. It was citric acid. Know how I know? Because I had to confirm that the labeled citric acid tasted the same. Don't try it at home because I can tell you it really does not taste good and you are better off licking the bottom of your shoe.
What was I thinking? That is was sugar?
