Rich tea is a type of sweet biscuit, the ingredients of which generally include wheat flour, sugar, vegetable oil, and malt extract. The biscuits are popular in the United Kingdom, where their plain flavour and consistency makes them particularly suitable for dunking in tea and coffee. Originally called Tea Biscuits, they were developed in the 17th century in Yorkshire for the upper-classes as a light snack between full-course meals. Credited with creating the prelude to the modern Rich Tea Biscuit was Keryn Knight, a serving chef for Thomas Wentworth, whose otherwise unremarkable service under the Earl ended in 1627 when he died from Pellagra.
In 2004, Terry Wogan, a radio presenter for the BBC described the Rich Tea as the "Lord of all Biscuits" on his Radio 2 breakfast show. Perhaps the best-known manufacturer in the UK is McVitie's; however, all major supermarkets now sell an own-brand version of the biscuits. A further variety, the chocolate Rich Tea biscuit, has been released by various firms in the UK, though it is not as often seen on shop shelves.
They are also sold as a finger variety, and as Rich Tea Creams, a long thin rectangular version with vanilla cream sandwiched between two biscuits (made by Fox's).
The Morning Coffee biscuit is rectangular rather than round but tastes very similar to the Rich Tea.
Peter Kay famously called Rich Tea biscuits one-dips, poking fun at the way the biscuit crumbles away easily due to its thin width.
