Worcestershire Sauce
You might not be able to pronounce it but you’re most likely are using it as a condiment. First made by the chemists John Wheeler Lea and William Perrins upon request by Governor of Bengal, based on a recipe brought from Asia. They made two batches as they were quite puzzled what’s the fuss about the sauce and they didn’t like it! Just like pretty much everything unwanted they stored it in the away only re-tasing it sometime later and instantly feeling the potential of a new food item and putting it out on sale in 1837. However up to this very day the original resicpe hasn’t been revealed and remains a secret.
