THE DOS

• Make sure you have all the necessary items
  Napkins, a tea pot (better to have two, see below), cups, saucers and a serving tray with at least two levels on which to display the sweet and savory snacks. The napkins will be smaller than usual, and should be opened fully and spread out on the lap when the tea is served.
• Heat the water
  The tea pot should always be warmed (rinsing it out with hot water), which ensures that the porcelain (often called “China” as that’s where the porcelain first originated) doesn’t undergo a “shock” when the boiling water is poured into it, which may lead to cracking.
• Add the tea leaves
  Calculate a teaspoon of leaves for each guest, plus one more “for the pot”. The boiling water should be poured straight over the leaves. If you place the tea leaves directly in the pot, you’ll need to use a filter over each cup. If instead, you don’t want the leaves to keep infusing in the hot water, you should use a tea “ball”. Infusion times vary from 3 to 5 minutes. True tea connoisseurs will have more than one pot: one for Indian black teas, one for Chinese green teas, one for aromatic teas, etc. Normally, two will suffice when serving: one for the tea and another for the hot water (although a kettle will do) when the tea gets too strong.
• Milk or lemon?
  Most Brits take tea with milk, a habit that originated from the fact that a drop of cold milk in the teacup prevented the dark, boiling tea to crack or stain the delicate porcelain. With today’s cups, you can safely pour the milk in afterwards. Sugar should be present in cubes or crystals, white and dark, and you should also provide honey or sweeteners.
• Savory or sweet
  Tea should be served with both savory and sweet snacks. There should be sandwiches, scones, pastries and cakes—served in this order: Savory (finger sandwiches with various fillings); neutral (scones, crumpets, buns); sweet (cakes, biscuits, pastries). It’s fundamental to serve each item in bite-sized portions, as tea should be consumed without cutlery.
• Etiquette
  The host or hostess can share the job of pouring the tea with close friends, but he or she should always pour the first cup. Good form dictates that the plate should be raised with the left hand, while the teacup should be held with the right hand. And watch those pinky fingers: they should be aligned with the other fingers.

THE DON'TS

• Don’t use tea bags instead of loose tea
• Don’t pour water when it’s scalding: the leaves will be burned and the flavor, ruined.
• Don’t let the tea infuse for too long in the teapot: for all the perfect infusion times, see the chart at the bottom of the page. Otherwise, the aroma will be compromised.
• Don’t stir the tea when it’s in the teapot or the cup
  Place the teaspoon at the “6 o’clock” position, and then gently move it to the “12 o’clock” position a couple of times. When done, place the teaspoon on the right side of the saucer.
• Don’t take the sugar cubes with your fingers. Use the special sugar tongs.
• Don’t lift your pinky finger when you raise the teacup.
• Don’t leave the slice of lemon in the cup as you sip your tea. It should be removed beforehand.
• Don’t prepare the sandwiches too far in advance (30 minutes is enough time): they’ll look old and wilted.
