Rich Tea

Rich tea is a type of sweet biscuit; the ingredients generally include wheat flour, sugar, vegetable oil and malt extract. Originally called Tea Biscuits, they were developed in the 17th century in Yorkshire, England for the upper classes as a light snack between full-course meals. One of the best-selling biscuits in the British Isles, the biscuit is also popular in Malta and Cyprus. The plain flavour and consistency of rich tea makes them particularly suitable for dunking in tea and coffee.
McVitie's have used the brand name "Rich Tea" since 1891 and remains the best-known manufacturer in the UK. Since 2000, most major supermarkets sell an own-brand version of the biscuits.
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.
In 2011 Prince William chose a groom's cake for his wedding reception made from 1,700 McVitie's rich tea biscuits and 17 kg of chocolate.
