It wasn't until the late 1800s in paris that a famous chef, Auguste Escoffier, made a new discovery about taste. First, he fried beef in a pan at a very high until was brown. Then he added a liquid and scraped the browned meat from the bottom of the pan. the taste of the browned meat stock wasn't sweet, salty , bitter, or sour. Escoffier was a chef, not a scientist, but he was sure he had found afifth taste.
