What is Worcestershire Sauce?

If you love to cook, chances are high that you’ve come across this ancient umami sauce with a tongue-twisting name. Worcestershire (pronounced “Wooster-sher”) sauce is a dark, complex condiment from England that adds rich flavors to soups, stews, marinades, and cocktails.

Definition and History of Worcestershire Sauce

Worcestershire sauce has a long and fascinating history dating back to the early 19th century when two chemists named John Lea and William Perrins accidentally invented it in Worcester city, England. The duo was trying to recreate the taste of an Indian sauce but ended up with a vile-tasting concoction they abandoned in their cellar for two years.

Intriguingly enough, they rediscovered the seemingly spoiled blend and tasted it afresh to discover its fermentation had created a unique savory taste unexpected only by them. Upon further experimentation on mixing herbs such as cloves and tamarind paste mixed into extracts of soybean molasses resulted in the creation of today’s Worcestershire sauce.

Common Ingredients and Flavor Profile

Worcestershire sauce often seems like an unassuming ingredient that uses few ingredients – vinegar, molasses (used also sometimes for Treacle), sugar syrup anchovies(gives fishy umaminess), garlic powder sweetened with either corn or barley syrup depending upon manufacture preference with fermented tamarind pulp which delivers tanginess- yet it’s potent in small quantities due to intensive months-long fermentation process produces complex overtones of bitterness combined with sweetness.

  • Salty: Anchovies give this popular condiment its distinctive salty flavor

  • Sweet: Molasses, sugar syrup and corn-syrup add sweetness to balance out the bitterness
