Tea in Scotland is always presented with milk or cream. You first pour boiling water into a teapot which should be made of pottery, not silver, then empty out the water and immediately put in one teaspoon of tea for every cup you will need, plus one 'for the pot'. Then fill the pot with boiling water and let the brew stand under a tea cozy for four minutes. Before pouring the tea, the cup should be covered with a strainer. If desired, add milk or cream to the cup before you pour the tea into it.
Tea is drunk at any hour of the day, and in any circumstances.
