Worcestershire sauce, the savory condiment known for its complex flavor is also one of our favorite oopsies, created in the early 19th century by chemists John Lea and William Perrins in Worcester, England. Lord Marcus Sandys, a nobleman returning to England from India, requested that Lea & Perrins replicate a sauce he had enjoyed during his travels. The chemists mixed a variety of ingredients, including anchovies, tamarind, molasses, and spices. The initial concoction was so disgusting that they set it aside in a cellar and forgot about it.
Months later, they rediscovered the sauce and found that it had fermented and aged into a rich, flavorful sauce. So, not only is this stuff hard to pronounce, but it's also proof that sometimes when you let stuff "spoil," it becomes delicious instead.
