Sauces and condiments from Worcester, England

Worcestershire sauce

Anchovies, tamarind, shallots, garlic and onions are soaked in vinegar for a year or more, the flavoured liquid is pressed out cold, and it is blended with molasses, sugar, salt and spices. The blend is matured for months in wooden casks, then briefly heated and bottled as a thin, tart, brown sauce.

At a glance

Anchovies, tamarind, shallots, garlic and onions are soaked in vinegar for a year or more, the flavoured liquid is pressed out cold, and it is blended with molasses, sugar, salt and spices. The blend is matured for months in wooden casks, then briefly heated and bottled as a thin, tart, brown sauce. Made in 5 steps over 12 months – 2 years. The longest step, steep anchovies, tamarind and alliums in vinegar, takes 12 months – 2 years (Shurtleff W. and Aoyagi A. 2012). Salt is 2.3–3.8 % (US Department of Agriculture 2015).

What makes this one different

Worcestershire sauce is a long vinegar steep, not a brine ferment like fish sauce. The anchovies are soaked in vinegar rather than salted alone, and the USDA specification requires the finished sauce to be free from fermentation.

Variants

  • Vegetarian Worcestershire sauceMade without anchovies.

Safety

The USDA specification sets pH 3.0–3.9, well below 4.6, the line US rules draw between acid and low-acid foods. It contains fish (anchovies) and usually barley malt vinegar, which matter for allergies.

History and sources

Every number is labelled with how it is known. How this atlas is made

John Wheeley Lea and William Henry Perrins, chemists in Broad Street, Worcester, began making the sauce in 1837. The packaging said it came 'from the recipe of a nobleman in the county', but the origin of the recipe is unclear, and the earliest known advertisement dates from 1840. Production moved to a new factory on Midland Road in 1896. A 1991 letter from the factory's general manager says soy sauce was a key ingredient until World War II, when hydrolysed vegetable protein replaced it.
