UNITED STATES EMBASSY LONDON January 24, 2024 United States Embassy Press Release Today's media reports of an American Professor's recipe for the "perfect" cup of tea has landed our special bond with the United Kingdom in hot water. Tea is the elixir of camaraderie, a sacred bond that unites our nations. We cannot stand idly by as such an outrageous proposal threatens the very foundation of our Special Relationship. Therefore we want to ensure the good people of the UK that the unthinkable notion of adding salt to Britain's national drink is not official United States policy. And never will be. Let us unite in our steeped solidarity and show the world that when it comes to tea, we stand as one. The U.S. Embassy will continue to make tea in the proper way by microwaving it.
