"US Chemist Recommends Adding Salt to Achieve the Perfect Cup of Tea"
Chemist Michelle Francl claims to have found the recipe for a perfect cup of tea, which includes adding a pinch of salt, energetic squeezing of the teabag, using short, stout mugs, pre-heating the mug or teapot, adding milk after pouring the tea, using larger teabags or loose leaves, and steeping decaffeinated tea for 30 seconds before rebrewing. Francl's research also suggests that a small squeeze of lemon juice can remove scum from the surface of the drink, and the aroma of tea is important, so it's best to remove the lid when drinking from a takeaway cup.
