If you want to make it iced, let the boiled black tea and milk cool, add sugar, and beat it with a foaming machine to get milk in the process of beating, which is easier to foam. Finally, add ice cubes.
Milk is a dry and hot drink, and black tea is a warm and cool drink. When they are mixed, they can be naturally mixed for health care. Their complementary effects can meet the needs of all parties.
Note that the intensity of boiling milk should be moderate, and the brewing time of black tea should be appropriate, not more than 3 minutes, to prevent bitterness. Black tea can be replaced by milk tea, and flowers or whipped cream can also be attached.
