Founded as West and Wyatt in 1706 , the company was purchased in 1830 by Edmund Crosse and Thomas Blackwell.
Crosse & Blackwell was one of the first companies to receive a Royal Warrant from the newly crowned Queen Victoria in 1837; in 1841 they became the first company to mass produce jam.
Crosse & Blackwell was also one of the first brands to use celebrity chefs for the development of their products, employing cooks of the caliber of French chef Alexis Soyer, the most celebrated cook in Victorian England and Charles Francatelli, an Anglo-Italian chef famous at that time for his cook books.
Crosse & Blackwell marketed a number of Soyer's sauces. They included a spicy one for gentlemen and a milder version for ladies, and "Soyer's Relish," a bestselling sauce that sold for more than 70 years.

The company also introduced Indian flavors and marketed products such as Captain White's Oriental Pickle and Curry Powder and Abdool Fygo's Chutney.
"The spirit of these products echoes Britain's expanding empire and reflects Crosse & Blackwell's global reach," MOLA said in a statement.
Bought in 1960 by Nestlé and now part of The J.M. Smucker Company, Crosse & Blackwell manufactured, bottled and packaged their products on the Soho factory until 1921.
A journalist's account of the time reported of a "very distinctive pungency to the surrounding atmosphere" and more directly, a "suffocating effluvium," according to the local Medical Officer for Health at the time.
Unfortunately, traces of the 200-year-old ketchup and the other Victorian delicacies can now be only found in the company's illustrated export catalogues.
"The glass and ceramics were discarded empty, so we were unable to find any content or residue," Jeffries said.
