Henderson's Relish is a condiment sauce produced in Sheffield, South Yorkshire, England, since 1885. Henry Henderson, a former miller and druggist, created the recipe. It is often compared to Worcestershire sauce due to its similar appearance and versatility but contains no anchovies, making it suitable for vegetarians and vegans. The recipe is a closely guarded secret known only to a few family members. Henderson's Relish is made from water, spirit vinegar, sugar, caramel, sugar syrup, salt, tamarinds, acetic acid, cayenne pepper, cloves, sweetener (saccharin), and garlic oil.
Henderson's Relish is manufactured by Hendersons (Sheffield) Ltd. The business was sold to Shaws of Huddersfield in 1910, and Charles Hinksman acquired majority control in 1940. The Freeman family runs Henderson's as a family business. The relish is often used to enhance the flavor of various dishes, including pies, stews, meats, chips, and cheeses. It is a staple in Sheffield and has a cult following in Yorkshire, where it is known as "Hendo's". A 284ml bottle typically retails between £1.50 and £2.49 in the UK, and around $4.95 to $7.99 in the US, depending on the retailer. It is available in various sizes, including 31ml, 142ml, 284ml, and 1L bottles.
