produced from the bush Camellia sinensis, is primarily important as one of the all-time great beverages of the world, a role which it first fulfilled in China and adjacent areas but which it has subsequently played (to packed tea houses one might say) in the rest of Asia, Europe (especially Britain), N. America, and Australia. Because of this role it has given its name to institutions such as high tea and the Japanese tea ceremony.
Tea made as in Tibet, with butter, may be said to constitute a food; and of course nourishment is obtained from tea drunk with milk, as it often is in Britain. For an example of the eating of tea leaves as a sort of relish, see lepet under Burma.
However, tea is also of some importance as a flavouring. Of the three main categories of tea (green, oolong, and black) the first and third are most commonly used for this purpose. Various sweet dishes, of which ice cream is the most obvious example, can be given a subtle tea flavour, but some is also used in some parts of the world for savoury dishes. Thus in Vietnam there is a tuna and pork dish in which these main ingredients are simmered in tea—ideally lotus-flavoured tea but ordinary black tea will do. One effect of the tea in a dish of this sort is to balance the fat.
Tea terminology is a matter of concern to tea drinkers and also to cooks who are using tea as a flavouring. When tea is used as a flavouring for food, recipes often just say ‘tea’, without being more specific. In fact, the choice of tea would often be important and is best made with some knowledge of at least the main types of tea, as briefly indicated here.
Teas, like wines and coffees, are classified in many ways, for full details of which one of the major works on the subject has to be consulted, especially the venerable but unrivalled two volumes by Ukers (1935). Here is no more than a sketch map.
The first and fundamental classification is by the extent, if any, of fermentation. This produces the three main categories referred to above:
Another fundamental classification is by country or region of origin. Here there are:
Other terms, which also include classification by size of leaf, include:
See also tisane.
Alan Davidson was a distinguished author and publisher, and one of the world's best-known writers on fish and fish cookery. In 1975 he retired early from the diplomatic service—after serving in, among other places, Washington, Egypt, Tunisia, and Laos, where he was British Ambassador—to pursue a fruitful second career as a food historian and food writer extraordinaire. Among his popular books are Seafood of South-East Asia, North Atlantic Seafood, and Mediterranean Seafood. In 2003, shortly before his death, he was awarded the Erasmus Prize for his contribution to European culture.
