"US Scientist's Tea Advice Sparks Transatlantic Controversy"

American scientist Michelle Francl has stirred controversy by suggesting that a pinch of salt can improve the taste of a cup of tea in her new book "Steeped: The Chemistry of Tea." This advice has sparked outrage among British tea-lovers, with the U.S. Embassy in London humorously intervening to reassure that adding salt to tea is not official U.S. policy. Francl's book delves into the chemical compounds in tea and offers tips on brewing a better cup, including using a pre-warmed pot, agitating the tea bag vigorously, and adding milk after the tea.
